[alsa-devel] [PATCH/alsa-lib trivial] hwdep: add missing declaration for snd_hwdep_poll_descriptors_count()

[Takashi Sakamoto]

The alsa-lib has 'snd_hwdep_poll_descriptors_count()' but hwdep.h has no
declaration for the function. No applications can call the function just
by including the header.

This commit adds a line to the file for this function.
