ALSA: gus: More constifications

2020-01-05T15:15:03+00:00

Apply const prefix to each possible place: the static resource tables, the volume table, etc. Just for minor optimization and no functional changes. Link: https://lore.kernel.org/r/20200105144823.29547-50-tiwai@suse.de Signed-off-by: Takashi Iwai

ALSA: gus: Support PCM sync_stop

2019-12-11T06:25:56+00:00

The driver invokes snd_pcm_period_elapsed() simply from the interrupt handler. Set card->sync_irq for enabling the missing sync_stop PCM operation. Link: https://lore.kernel.org/r/20191210063454.31603-43-tiwai@suse.de Signed-off-by: Takashi Iwai

ALSA: gus: constify pnp_card_device_id

2017-08-17T10:42:25+00:00

pnp_card_device_id are not supposed to change at runtime. All functions working with pnp_card_device_id provided by work with const pnp_card_device_id. So mark the non-const structs as const. Signed-off-by: Arvind Yadav Signed-off-by: Takashi Iwai

Annotate hardware config module parameters in sound/isa/

2017-04-20T11:02:32+00:00

When the kernel is running in secure boot mode, we lock down the kernel to prevent userspace from modifying the running kernel image. Whilst this includes prohibiting access to things like /dev/mem, it must also prevent access by means of configuring driver modules in such a way as to cause a device to access or modify the kernel image. To this end, annotate module_param* statements that refer to hardware configuration and indicate for future reference what type of parameter they specify. The parameter parser in the core sees this information and can skip such parameters with an error message if the kernel is locked down. The module initialisation then runs as normal, but just sees whatever the default values for those parameters is. Note that we do still need to do the module initialisation because some drivers have viable defaults set in case parameters aren't specified and some drivers support automatic configuration (e.g. PNP or PCI) in addition to manually coded parameters. This patch annotates drivers in sound/isa/. Suggested-by: Alan Cox Signed-off-by: David Howells cc: Jaroslav Kysela cc: Takashi Iwai cc: alsa-devel@alsa-project.org

ALSA: wss: Remove (almost) always NULL parameters

2015-01-02T15:30:08+00:00

Most callers of snd_wss_pcm(), snd_wss_timer() and snd_cs4236_pcm() pass NULL as the last parameter, some callers pass a pointer but never use it after the function has been called and only a few callers pass a pointer and actually use it. The later is only the case for snd_wss_pcm() for snd_cs4236_pcm() and it is possible to get the same PCM object by accessing the pcm field of the snd_wss struct that was passed as the first parameter. This function removes the last parameters from the functions mentioned above and updates the callers which used it to use chip->pcm instead. This allows us to slightly simplify the functions since they don't have to check and set the last parameter anymore which makes the code slightly shorter and cleaner.

ALSA: gus: Remove always NULL parameters

2015-01-02T15:27:42+00:00

snd_gf1_pcm_new() and snd_gf1_rawmidi_new() take a pointer to a pointer of a PCM/MIDI where if this parameter is provided the newly allocated object is stored. All callers pass NULL though, so remove the parameter. This makes the code a bit cleaner and shorter. Signed-off-by: Lars-Peter Clausen Signed-off-by: Takashi Iwai

ALSA: gus: remove checks for CONFIG_SND_DEBUG_ROM

2014-05-30T08:12:10+00:00

Checks for CONFIG_SND_DEBUG_ROM were added in v2.5.5 but a Kconfig symbol SND_DEBUG_ROM was never added. These checks have always evaluated to false. Remove them and the printk()s they hide. Signed-off-by: Paul Bolle Signed-off-by: Takashi Iwai

ALSA: don't push static constants on stack for %*ph
