== SRU Justification ==

Commit 73b3c06f83fbc43b02f1fe8aa770c37c3becb463 ("ALSA: hda/idt - Fix
power-map for speaker-pins with some HP laptops") has been introduced
to the Precise kernel from a stable update.  However, this commit
breaks the sound on same HP laptops.

== Fix ==

A backport of commit 6e1c39c6b00d9141a82c231ba7c5e5b1716974b2 from
git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git (branch
fix/hda) fixes this issue.

== Impact ==

Users with HP laptops with the SigmaTel STAC92xx (e.g., HP Pavilion
dv6 Notebook PC) will not be able to play audio.

== Test Case ==

Try to play some audio on a system that has a SigmaTel STAC92xx.
