2024-05-09ALSA: ac97: legacy: Add missing module descriptionGravatar Takashi Iwai 1-0/+1
Now that make W=1 starts complaining the lack of MODULE_DESCRIPTION(), let's add the missing information.

2023-12-30ALSA: mark all struct bus_type as constGravatar Greg Kroah-Hartman 1-1/+1
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.

2023-03-20ALSA: ac97: Remove redundant driver match functionGravatar Lizhe 1-11/+0
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.

2020-01-03ALSA: ac97: Treat snd_ac97_bus_ops as constGravatar Takashi Iwai 1-1/+1
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 <tiwai@suse.de>

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus 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.
2015-08-21ALSA: ac97: Switch to dev_pm_opsGravatar Lars-Peter Clausen 1-26/+0
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.

2015-07-23ALSA: ac97: Add helper function to reset the AC97 deviceGravatar Lars-Peter Clausen 1-0/+62
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.

2006-12-12[PATCH] remove config ordering/dependency between ucb1400-ts and sound subsystemGravatar Nicolas Pitre 1-0/+72
Commit 2d4ba4a3b9aef95d328d74a17ae84f8d658059e2 introduced a dependency that was never meant to exist when the ac97_bus.c module was created. Move ac97_bus.c up the directory hierarchy to make sure it is built when selected even if sound is configured out so things work as originally intended.
