Subject: [PATCH 6/6] ARM: OMAP: OSK led fixes

From: David Brownell <david-b@...bell.net>

Bugfixes for the OSK led support:

 - Fix Kconfig merge glitches:  Mistral handles idle and timer leds just fine
 - Fix pm_suspend() runtime botch:  can't sleep, so can't touch tps65010 leds

Improvements:
 - Switch sense of Mistral idle led, so idle == off

Probably the TPS65010 leds should be handled only by the "new led" API.
