[alsa-devel] [PATCH alsa-lib 06/12] pcm: hw: use helper function to query status/control data after REWIND/FORWARD call

[Takashi Sakamoto]

When operating rewind/forward, appl_ptr is recalculated by ALSA PCM core
in kernel space. Therefore, after the operations, applications should
query appl_ptr.

This commit utilizes a helper function for this purpose. The value of
avail_min is relevant to this operation, thus just queried.
