Tinyalsa pcm_wait() function does not wait on POLLIN events, preventing it to be used when recording audio data. This allows pcm_wait to wait on POLLIN events.

ALSA supports reporting of pcm_delay, make that availble to the users of tinyalsa too Change-Id: Ic460f5c55137d263fdf7b142503d3bd52c4b7ebd Signed-off-by: Hardik T Shah <hardik.t.shah@intel.com> Signed-off-by: Apelete Seketeli <apeletex.seketeli@intel.com> Signed-off-by: Thomas Cahuzac <thomasx.cahuzac@intel.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com> Signed-off-by: David Wagner <david.wagner@intel.com>
The users of tinyalsa had no way of knowing on which subdevice a stream had been created. A new API, "unsigned int pcm_get_subdevice(struct *pcm)" returns it. This information is filled during the pcm_open() Change-Id: Ie866e10e06ce6691ede09e2ca46a24441723ea8b Signed-off-by: David Wagner <david.wagner@intel.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com>

Same as tinyalsa#48 but the pcm_get_delay() function has been modified to follow the same return style as all other tinyalsa functions.
