[alsa-devel] [PATCH 0/2] Mic fixes for Acer AO756 and C7

The mic sense pin on these systems always indicates mic present if the
combo jack is empty.  The Mic presence must be ignored unless the
Headphone jack is plugged.  To handle this, introduce the concept of a
jack that is gated by the state of another jack.  Does this method seem
reasonable?  Am I missing a better way to handle it?

The second patch also fixes up the pin configs for the A0756 netbook,
the C7 ChromeOS variant doesn't need these but they don't hurt either.

Dylan Reid (2):
  ALSA: hda - Allow jack state to depend on another jack.
  ALSA: hda - Fix Acer Aspire models with analog mics.
