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

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.
