Commit f3ee99087c8ca0ecfdd549ef5a94f557c42d5428 ("ASoC: tegra: Allow
24bit and 32bit samples") added 24-bit and 32-bit support for to the
Tegra30 I2S driver. However, there are two additional commits that are
also needed to get 24-bit and 32-bit support to work correctly. These
commits are not yet applied because there are still some review comments
that need to be addressed. With only this change applied, 24-bit and
32-bit support is advertised by the I2S driver, but it does not work and
the audio is distorted. Therefore, revert this patch for now until the
other changes are also ready.
Furthermore, a clock issue with 24-bit support has been identified with
this change and so if we revert this now, we can also fix that in the
updated version.

Stopping of one stream is killing the other stream when they
are running simultaneously. This is because, IER register is
cleared which disables I2S and overrides any other block enables.
Clearing IER register only when all streams on a channel are disabled,
fixes the issue.

Multiple Intel ASoC machine drivers repeat the same pattern in their
.late_probe() methods: they first check whether the common HDMI codec
driver is used, if not, they proceed by linking the legacy HDMI
driver to each HDMI port. While doing that they use some
inconsistent code:
1. after the loop they check, whether the list contained at least one
element and if not, they return an error. However, the earlier
code to use the common HDMI driver uses the first element of the
same list without checking. To fix this we move the check to the
top of the function.
2. some of those .late_probe() implementations execute code, only
needed for the common HDMI driver, before checking, whether the
driver is used. Move the code to after the check.
3. Some of those functions also perform a redundant initialisation of
the "err" variable.
This patch fixes those issues.

Check if DMA pages were successfully allocated in initialization
before calling free. For many types of memory (like sgbufs)
the extra free is harmless, but not all backends track allocation
state, so add an explicit check.

The initial intent of releasing resources in the .remove does not work
well with HDaudio codecs. If the probe_continue() fails in a work
queue, e.g. due to missing firmware or authentication issues, we don't
release any resources, and as a result the kernel oopses during
suspend operations.
The suggested fix is to release all resources during errors in
probe_continue(), and use fw_state to track resource allocation
state, so that .remove does not attempt to release the same
hardware resources twice. PM operations are also modified so that
no action is done if DSP resources have been freed due to
an error at probe.

It is possible to create invalid topology that will cause a kernel
Oops when trying to allocate buffers for a NULL substream.
Specifically such an Oops was caused by a topology, where a DAI on a
capture pipeline was referencing the PCM ID from a playback pipeline.
Fix the Oops by explicitly checking for NULL.

If we play audio back to back, which kills one playback
and immediately start another, we can hear clicks.
This patch fixes the issue.

Change HDA probe behaviour slightly so that i915 power is not
turned off if i915 audio codecs are found in the initial probe done
by SOF Intel driver, and power is kept on until HDA codec driver
probe runs.
This will reduce number of mode sets on platforms with low
minimum CDCLK (like GLK) and brings the SOF probe sequence closer
to legacy HDA driver in terms of i915 audio codec power management.

The current interface to control i915 display power is misleading.
The hda_codec_i915_get() and hda_codec_i915_put() names suggest
a refcounting based interface. This is confusing as no refcounting
is done and the underlying HDAC library interface does not support
refcounts eithers.
Clarify the code by replacing the functions with a single
hda_codec_i915_display_power() that is aligned with
snd_hdac_display_power().

Commit 08df0d9a00f7 ("ASoC: max98090: revert "ASoC: max98090: fix lockdep
warning"") provided a good rationale for removing separate lock for the
SHDN register access. However it restored the lockdep warning during the
system boot. To silence the lockdep warning, mark the mutex taken in the
max98090_shdn_save() function with the lockdep class dedicated for the
runtime DAPM operations: SND_SOC_DAPM_CLASS_RUNTIME. This finally fixes
the following lockdep warning observed on Exynos4412-based Odroid U3
board:

If dyn_pcm_assign is set, different jack objects are being created
for pcm and pins.
If dyn_pcm_assign is set, generic_hdmi_build_jack() calls into
add_hdmi_jack_kctl() to create and track separate jack object for
pcm. Like sync_eld_via_acomp(), hdmi_present_sense_via_verbs() also
need to report status change of the pcm jack.
Rename pin_idx_to_jack() to pin_idx_to_pcm_jack(). Update
hdmi_present_sense_via_verbs() to report plug state of pcm jack
object. Unlike sync_eld_via_acomp(), for !acomp drivers the pcm
jack's plug state must be consistent with plug state
of pin's jack.

The firmware loading ioctl that is implemented for hdsp hwdep device
takes the reference of the address pointer, hence the current code is
rather confusing. Also, due to the recent change in uapi header,
sparse also complains about the cast.
This patch tries to improve the readability by converting the
straightforward copy_from_user of the whole struct (which contains
only the pointer).

The recent sound/emu10k1.h uapi header change by the commit
2e4688676392 ("ALSA: emu10k1: Make uapi/emu10k1.h compilable again")
made sparse angry because of the inconsistency of __user annotation
and the own ctl id struct that were changed in uapi header.
This patch addresses those by adjusting the cast and annotations
properly again.

The Scarlett gen2 mixer quirk code defines a few record types to
communicate via USB hub, and those must be all little-endian.
This patch changes the field types to LE to annotate endianess
properly. It also fixes the incorrect usage of leXX_to_cpu() in a
couple of places, which was caught by sparse after this change.

Since we have a bitwise definition of snd_pcm_state_t and use it for
certain struct fields, a few new (and years old) sparse warnings came
up. This patch is an attempt to cover them.
- The state fields in snd_pcm_mmap_status* and co are all defined as
snd_pcm_state_t type now
- The PCM action callbacks take snd_pcm_state_t argument as well;
some actions taking special values got the explicit cast and
comments
- For the PCM action that doesn't need an extra argument receives
ACTION_ARG_IGNORE instead of ambiguous 0
While we're at it, the boolean argument is also properly changed to
bool and true/false, as well as a slight refactoring of PCM pause
helper function to make easier to read.
No functional changes, just shutting up chatty sparse.

ALSA PCM core recently introduced a new managed PCM buffer allocation
mode that does allocate / free automatically at hw_params and
hw_free. However, it overlooked the code path directly calling
hw_free PCM ops at releasing the PCM substream, and it may result in a
memory leak as spotted by syzkaller when no buffer preallocation is
used (e.g. vmalloc buffer).
This patch papers over it with a slight refactoring. The hw_free ops
call and relevant tasks are unified in a new helper function, and call
it from both places.

Tegra HDA has FIFO size which can hold upto 10 audio frames to support
DVFS. When HDA DMA RUN bit is set to 0 to stop the stream, the DMA RUN
bit will be cleared to 0 only after transferring all the remaining audio
frames queued up in the fifo. This is not in sync with spec which states
the controller will stop transmitting(output) in the beginning of the
next frame for the relevant stream.
The above behavior with Tegra HDA was resulting in machine check error
during the system suspend flow with active audio playback with below kernel
error logs.
[ 33.524583] mc-err: [mcerr] (hda) csr_hdar: EMEM address decode error
[ 33.531088] mc-err: [mcerr] status = 0x20000015; addr = 0x00000000
[ 33.537431] mc-err: [mcerr] secure: no, access-type: read, SMMU fault: none
This was due to the fifo has more than one audio frame when the DMA
RUN bit is set to 0 during system suspend flow and the timeout handling in
snd_hdac_stream_sync() was not designed to handle this scenario. So the
DMA will continue running even after timeout hit until all remaining
audio frames in the fifo are transferred, but the suspend flow will try
to reset the controller and turn off the hda clocks without the knowledge
of the DMA is still running and could result in mc-err.
The above issue can be resolved by doing stream reset with the help of
snd_hdac_stream_reset() which would ensure the DMA RUN bit is cleared
if the timeout was hit in snd_hdac_stream_sync().

Pull ceph fixes from Ilya Dryomov:
- a set of patches that fixes various corner cases in mount and umount
code (Xiubo Li). This has to do with choosing an MDS, distinguishing
between laggy and down MDSes and parsing the server path.
- inode initialization fixes (Jeff Layton). The one included here
mostly concerns things like open_by_handle() and there is another one
that will come through Al.
- copy_file_range() now uses the new copy-from2 op (Luis Henriques).
The existing copy-from op turned out to be infeasible for generic
filesystem use; we disable the copy offload if OSDs don't support
copy-from2.
- a patch to link "rbd" and "block" devices together in sysfs (Hannes
Reinecke)
... and a smattering of cleanups from Xiubo, Jeff and Chengguang.

The rbd driver already provides additional information in sysfs
under /sys/bus/rbd, so we should set the 'device' link in the block
device to reference this information.

At the same time, switch to __func__ to get rid of the checkpatch

Instead of using the copy-from operation, switch copy_file_range to the
new copy-from2 operation, which allows to send the truncate_seq and
truncate_size parameters.
If an OSD does not support the copy-from2 operation it will return
-EOPNOTSUPP. In that case, the kernel client will stop trying to do
remote object copies for this fs client and will always use the generic
VFS copy_file_range.

gcc -O3 warns about a dummy variable that is passed
down into rbd_img_fill_nodata without being initialized:
drivers/block/rbd.c: In function 'rbd_img_fill_nodata':
drivers/block/rbd.c:2573:13: error: 'dummy' is used uninitialized in this function [-Werror=uninitialized]
fctx->iter = *fctx->pos;
Since this is a dummy, I assume the warning is harmless, but
it's better to initialize it anyway and avoid the warning.

It's possible to pass the mount helper a server path that has more
than one contiguous slash character. For example:
$ mount -t ceph 192.168.195.165:40176:/// /mnt/cephfs/
In the MDS server side the extra slashes of the server path will be
treated as snap dir, and then we can get the following debug logs:
ceph: mount opening path //
ceph: open_root_inode opening '//'
ceph: fill_trace 0000000059b8a3bc is_dentry 0 is_target 1
ceph: alloc_inode 00000000dc4ca00b
ceph: get_inode created new inode 00000000dc4ca00b 1.ffffffffffffffff ino 1
ceph: get_inode on 1=1.ffffffffffffffff got 00000000dc4ca00b
And then when creating any new file or directory under the mount
point, we can hit the following BUG_ON in ceph_fill_trace():
BUG_ON(ceph_snap(dir) != dvino.snap);
Have the client ignore the extra slashes in the server path when
mounting. This will also canonicalize the path, so that identical mounts
can be consilidated.
1) "//mydir1///mydir//"
2) "/mydir1/mydir"
3) "/mydir1/mydir/"
Regardless of the internal treatment of these paths, the kernel still
stores the original string including the leading '/' for presentation
to userland.

The m_num_mds here is actually the number for MDSs which are in
up:active status, and it will be duplicated to m_num_active_mds,
so remove it.
Add possible_max_rank to the mdsmap struct and this will be
the correctly possible largest rank boundary.
Remove the special case for one mds in __mdsmap_get_random_mds(),
because the validate mds rank may not always be 0.

In the debug logs about the di->offset or ctx->pos it is in hex
format, but some others are using the dec format. It is a little
hard to read.
For the xattr version, it is u64 type, using a shorter type may
truncate it.

Currently, we could have an open-by-handle (or NFS server) call
into the filesystem and start working with an inode before it's
properly filled out.
Don't clear I_NEW until we have filled out the inode, and discard it
properly if that fails. Note that we occasionally take an extra
reference to the inode to ensure that we don't put the last reference in
discard_new_inode, but rather leave it for ceph_async_iput.

If max_mds > 1 and a request is submitted that chooses a random mds
rank, and the relating session is not opened yet, the request will wait
until the session has been opened and resend again.
Every time the request goes through __do_request, it will release the
req->session first and choose a random one again, which may be a
completely different rank than the one it just waited on.
In the worst case, it will open all the mds sessions one by one just
before the request can be successfully sent out.

If all the MDS daemons are down for some reason, then the first mount
attempt will fail with EIO after the mount request times out. A mount
attempt will also fail with EIO if all of the MDS's are laggy.
This patch changes the code to return -EHOSTUNREACH in these situations
and adds a pr_info error message to help the admin determine the cause.

When reconnecting the session but if it is denied by the MDS due
to client was in blacklist or something else, kclient will receive
a session close reply, and we will never see the important log:
"ceph: mds%d reconnect denied"
And with the confusing log:
"ceph: handle_session mds0 close 0000000085804730 state ??? seq 0"
Let's keep the session state until its memories is released.
