Pull chrome platform updates from Benson Leung:
"CrOS EC:
- Refactoring of some of cros_ec's headers:
include/linux/mfd/cros_ec.h now removed, new cros_ec.h added to
drivers/platform/chrome which contains shared operations of cros_ec
transport drivers.
- Response tracing in cros_ec_proto
Wilco EC:
- Fix unregistration order.
- Fix keyboard backlight probing on systems without keyboard
backlight
- Minor cleanup (newlines in printks, COMPILE_TEST)
Misc:
- chromeos_laptop converted to use i2c_new_scanned_device instead of
i2c_new_probed_device"

This header file now only includes the cros_ec_dev struct, however, is the
'include/linux/platform_data/cros_ec_proto.h' who contains the definition of
all the Chrome OS EC related structs. There is no reason to have a
separate include for this struct so move to the place where other
structs are defined. That way, we can remove the include itself, but also
simplify the common pattern
#include <linux/mfd/cros_ec.h>
#include <linux/platform_data/cros_ec_proto.h>
for a single include
#include <linux/platform_data/cros_ec_proto.h>
The changes to remove the cros_ec.h include were generated with the
following shell script:
git grep -l "<linux/mfd/cros_ec.h>" | xargs sed -i '/<linux\/mfd\/cros_ec.h>/d'

This device does not function correctly in raw mode in kernel
versions validating buffer sizes in bulk mode. It erroneously
announces 16 bits per pixel instead of 12 for NV12 format, so it
needs this quirk to fix computed frame size and avoid legitimate
frames getting discarded.

Looking into the output from usbmon, the interesting part is the
following data packet:
ffff880069c63e00 30710169 C Ci:1:002:0 0 143 = 09028f00 01030080
00090403 00000e01 00000924 03000103 7c003328 010204db
If we drop the lead configuration and interface descriptors, we're left
with an output terminal descriptor describing a generic display:
/* Output terminal descriptor */
buf[0] 09
buf[1] 24
buf[2] 03 /* UVC_VC_OUTPUT_TERMINAL */
buf[3] 00 /* ID */
buf[4] 01 /* type == 0x0301 (UVC_OTT_DISPLAY) */
buf[5] 03
buf[6] 7c
buf[7] 00 /* source ID refers to self! */
buf[8] 33
The problem with this descriptor is that it is self-referential: the
source ID of 0 matches itself! This causes the 'struct uvc_entity'
representing the display to be added to its chain list twice during
'uvc_scan_chain()': once via 'uvc_scan_chain_entity()' when it is
processed directly from the 'dev->entities' list and then again
immediately afterwards when trying to follow the source ID in
'uvc_scan_chain_forward()'
Add a check before adding an entity to a chain list to ensure that the
entity is not already part of a chain.

When aligning the format the pixel format that is being processed shall
be used to figure out alignment constraints, not the currently active
pixel format. The alignment might be part of a try operation and shall
not be effected by the active format. Fix this by looking at the correct
pixel format.

Make sure to use the current alternate setting, which need not be the
first one by index, when verifying the endpoint descriptors and
initialising the URBs.
Failing to do so could cause the driver to misbehave or trigger a WARN()
in usb_submit_urb() that kernels with panic_on_warn set would choke on.

In the case where v4l2_event_dequeue fails the structure ev is not
being filled and this garbage data from the stack is being copied
to the ev32 structure and being copied back to userspace on the
VIDIOC_DQEVENT_TIME32 ioctl. Fix this by ensuring the ev structure
is zero'd to ensure uninitialized data is not leaked back.

Despite using M2M in both the decoder and encoder, this driver used
vb2_v4l2_buffer as its base buffer structure, and placed a list_head
right after the buffer declaration in order to match the layout of a
v4l2_m2m_buffer. This is very dangerous as it means the driver will
break should the layout of v4l2_m2m_buffer change.
Fix this by directly using v4l2_m2m_buffer and updating the sites that
accessed the buffer accordingly.

bdisp_device_run()
The driver may sleep while holding a spinlock.
The function call path (from bottom to top) in Linux 4.19 is:
drivers/media/platform/sti/bdisp/bdisp-hw.c, 385:
msleep in bdisp_hw_reset
drivers/media/platform/sti/bdisp/bdisp-v4l2.c, 341:
bdisp_hw_reset in bdisp_device_run
drivers/media/platform/sti/bdisp/bdisp-v4l2.c, 317:
_raw_spin_lock_irqsave in bdisp_device_run
To fix this bug, msleep() is replaced with udelay().
This bug is found by a static analysis tool STCheck written by myself.

The memset() got moved out of the check for _IOC_NONE, so passing a
made-up command number with a size but no direction would allow clearing
data on user-provided pointers.
Move video_get_user() back into the _IOC_NONE check where it belongs.

The IR device on Hi3796CV300 SoC is mostly same as hix5hd2, except the
following two things.
- IR_CLK offset is 0x60 instead of 0x48.
- It needs to set an extra bit in IR_ENABLE register to enable IR.
The following changes are made to deal with them.
- Define a SoC specific data to accommodate IR_CLK offset and the flag
telling requirement of extra enable bit.
- Create function hix5hd2_ir_enable() to handle IR enabling. The original
hix5hd2_ir_enable() is all about managing IR clock, so gets renamed
to hix5hd2_ir_clk_enable().
- Device table hix5hd2_ir_table[] gets moved forward, as it's being
used by hix5hd2_ir_probe() now.

Resetting buf without resetting pusi_seen at a channel-switch can lead
to copying the rest of a section to the start of buf, but treating it as
a complete section, when the next pusi arrives.
EIT-sections starting without valid header were randomly received during
an EIT-scan on a transponder.
