[PATCH 3.2 077/125] ALSA: hda - Add quirk for external mic on Lifebook U904

[Ben Hutchings]

3.2.61-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: David Henningsson <david.henningsson@xxxxxxxxxxxxx>

commit 2041d56464a067461d7cc21734a0f024587ed2ff upstream.

According to the bug reporter (ÐÐÐÐÐÐ ÐÐÐÐÐ), the external mic
starts to work and has proper jack detection if only pin 0x19
is marked properly as an external headset mic.
