Takashi Iwai [Tue, 31 Jul 2012 08:16:59 +0000 (10:16 +0200)]
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".
