[alsa-devel] [PATCH 0/2] ALSA: pcm: remove unused local commands

[Takashi Sakamoto]

Hi,

A callback of 'struct snd_pcm_ops.ioctl' is internally used for ALSA
pcm core to communicate to each drivers for some purposes; e.g. ask the
size of FIFO in handled devices. However, in 'include/sound/pcm.h',
there're some commands for the callback, which has never been used.

This commit removes the unused commands to prevent developers from
undocumented and unreferenced features.

Takashi Sakamoto (2):
  ALSA: pcm: remove SNDRV_PCM_IOCTL1_INFO internal command
  ALSA: pcm: remove SNDRV_PCM_IOCTL1_GSTATE internal command
