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>
