2019-06-05treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 345Thomas Gleixner
Based on 1 normalized pattern(s): licensed under the terms of the gnu general public license version 2 extracted by the scancode license scanner the SPDX license identifier GPL-2.0-only has been chosen to replace the boilerplate/reference in 88 file(s).

2019-01-21ALSA: pcm: Unify snd_pcm_group initializationTakashi Iwai
There are multiple open codes that initialize the same object. Create a common helper function instead. Also, use kzalloc() to be safer at creating a group object, and move the initialization out of the critical section. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2018-07-04ALSA: pcm: trace XRUN event at injection, tooTakashi Iwai
The PCM xrun injection triggers directly snd_pcm_stop() without the standard xrun handler, hence it's not recorded on the event buffer. Ditto for snd_pcm_stop_xrun() call and SNDRV_PCM_IOCTL_XRUN ioctl. They are inconvenient from the debugging POV. Let's make them to trigger XRUN via the standard helper more consistently.

2018-04-17ALSA: pcm: Clean up with snd_pcm_avail() and snd_pcm_hw_avail() helpersTakashi Iwai
Introduce two new direction-neutral helpers to calculate the avail and hw_avail values, and clean up the code with them. The two separated forward and rewind functions are gathered to the unified functions. No functional change but only code reductions.

2017-06-12ALSA: pcm: unify codes to operate application-side position on PCM bufferTakashi Sakamoto
In a series of recent work, ALSA PCM core got some arrangements to handle application-side position on PCM buffer. However, relevant codes still disperse to two translation units This commit unifies these codes into a helper function.

2017-06-09ALSA: pcm: localize snd_pcm_hw_params_choose()Takashi Sakamoto
As of v4.12, snd_pcm_hw_params_choose() is just called in a process context of ioctl(2) with SNDRV_PCM_IOCTL_HW_PARAMS. The function locates in a different file, which has no tracepoints. This commit moves the function to a file with the tracepoints for later commit. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2017-05-26ALSA: pcm: add local header file for snd-pcm moduleTakashi Sakamoto
Several files are used to construct PCM core module, a.k.a snd-pcm. Although available APIs are described in 'include/sound/pcm.h', some of them are not exported as symbols in kernel space. Such APIs are just for module local usage. This commit adds module local header file and move some function prototypes into it so that scopes of them are controlled properly and developers get no confusion from unavailable symbols.
