[PATCH 3.16 137/346] ALSA: hda - On-board speaker fixup on ACER Veriton

[Ben Hutchings]

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

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

From: Shrirang Bagul <shrirang.bagul@xxxxxxxxxxxxx>

commit 9b51fe3efe4c270005e34f55a97e5a84ad68e581 upstream.

On Acer Veriton machines, codec with subsystem-id 0x1b0a01b8 the port at
0x15 is configured by default as an Internal Speaker (0x90170120).
However, no physical is speaker installed on-board. This patch adds a quirk
which disables the physical connection on this pin.
