Subject: [patch 017/149] ALSA: hda: Use LPIB for Acer Aspire 5110

2.6.32-stable review patch.  If anyone has any objections, please let us know.

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

From: Daniel T Chen <crimsun@...ntu.com>

commit 7a68be94e22e7643038726ebc14360752a91800b upstream.

BugLink: https://launchpad.net/bugs/583983

Symptom: on a significant number of hardware, booting from a live cd
results in capture working correctly, but once the distribution is
installed, booting from the install results in capture not working.

Test case: boot from Ubuntu 10.04 LTS live cd; capture works correctly.
Install to HD and reboot; capture does not work. Reproduced with 2.6.32
mainline build (vanilla kernel.org compile).

Resolution: add SSID for Acer Aspire 5110 to the position_fix quirk
table, explicitly specifying the LPIB method.

I'll be sending additional patches for these SSIDs as bug reports are
confirmed.
