ALSA: ac97: Fix kernel-doc warning for snd_ac97_reset

2025-11-06T09:52:43Z

kernel-doc populated the below warning for the non static function "snd_ac97_reset". "Warning: ./sound/ac97_bus.c:56 No description found for return value of 'snd_ac97_reset'". Added the return values as per the kernel-doc format. Signed-off-by: HariKrishna Sagala Link: https://patch.msgid.link/20251105105229.112172-2-hariconscious@gmail.com Signed-off-by: Takashi Iwai

ALSA: ac97: legacy: Add missing module description

Now that make W=1 starts complaining the lack of MODULE_DESCRIPTION(), let's add the missing information.

ALSA: mark all struct bus_type as const

2023-12-30T09:10:41Z

Now that the driver core can properly handle constant struct bus_type, move all of the sound subsystem struct bus_type structures as const, placing them into read-only memory which can not be modified at runtime. Note, this fixes a duplicate definition of ac97_bus_type, which somehow was declared extern in a .h file, and then static as a prototype in a .c file, and then properly later on in the same .c file. Amazing that no compiler warning ever showed up for this. Cc: Jaroslav Kysela Cc: Takashi Iwai Cc: Dawei Li Cc: Yu Liao Cc: "Rafael J.

ALSA: ac97: Remove redundant driver match function

2023-03-20T07:50:02Z

If there is no driver match function, the driver core assumes that each candidate pair (driver, device) matches, see driver_match_device() Drop the bus's match function that always returned 1 and so implements the same behaviour as when there is no match function.

ALSA: ac97: Treat snd_ac97_bus_ops as const

2020-01-03T08:24:08Z

This is a preliminary patch to allow const for snd_ac97_bus_ops definitions in each driver's code. The ops reference is read-only, hence it can be declared as const for further optimization. There should be no functional changes by this patch. Link: https://lore.kernel.org/r/20200103081714.9560-23-tiwai@suse.de Signed-off-by: Takashi Iwai

Merge tag 'asoc-v4.2-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus

2015-08-31T14:25:22Z

ASoC: Updates for v4.3 Not many updates to the core here, but an awful lot of driver updates this time round: - Factoring out of AC'97 reset code into the core - New drivers for Cirrus CS4349, GTM601, InvenSense ICS43432, Realtek RT298 and ST STI controllers. - Machine drivers for Rockchip systems with MAX98090 and RT5645 and RT5650. - Initial driver support for Intel Skylake devices. - A large number of cleanups for Lars-Peter Clausen and Axel Lin.

ALSA: ac97: Switch to dev_pm_ops

2015-08-21T17:27:23Z

Convert the ac97_bus from legacy suspend/resume callbacks to dev_pm_ops. Since there isn't anything special to do at the bus level the bus driver does not have to implement any callbacks. The device driver core will automatically pick up and execute the device's PM ops. As there is only a single AC'97 driver implementing suspend and resume, update both the core and driver at the same time to avoid unnecessary code churn. While we are at it also drop the ifdefs around the suspend/resume functions to increase compile test coverage. Signed-off-by: Lars-Peter Clausen Acked-by: Dmitry Torokhov Signed-off-by: Takashi Iwai

ALSA: ac97: Add helper function to reset the AC97 device

2015-07-23T16:33:14Z

There is currently a lot of code duplication in ASoC drivers regarding the reset handling of devices. This patch introduces a new generic reset function in the generic AC'97 framework that can be used to replace most the custom reset functions.
