Through a quick glance, the code changes look OK in general.
But please correct the subject prefix.  For non-ASoC patches (that
begin with either "hda" or "sound" in this patch set) should be with
"ALSA: hda: xxx" or such.

Also, although I respect the spirit of Haiku, the patch logs could be
a bit more verbose and descriptive, and the texts can be folded at the
right column.  Some patch descriptions are too short, e.g. patch 15
doesn't mention about the new usleep_range() addition in the code.


thanks,
