This patch corrects the full-scale volume setting logic. On certain
platforms, the full-scale volume bit is required. The current logic
mistakenly sets this bit and incorrectly clears reserved bit 0, causing
the headphone output to be muted.

It should be "Fixes" :)
Also, the tag should be in the form of
  Fixes: $ID ("$SUBJECT")
with quotes.  I fixed and applied now.


thanks,
