[ 100/109] ALSA: hda - Fix polarity of mute LED on HP Mini 210

[Greg Kroah-Hartman]

From: Greg KH <gregkh@xxxxxxxxxxxxxxxxxxx>

3.4-stable review patch.  If anyone has any objections, please let me know.

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

From: Takashi Iwai <tiwai@xxxxxxx>

commit ff8a1e274cbc11da6b57849f925b895a212b56c9 upstream.

The commit a3e199732b made the LED working again on HP Mini 210 but
with a wrong polarity.  This patch fixes the polarity for this
machine, and also introduce a new model string "hp-inv-led".
