Thanks, I'll queue these both for Grant for the 3.0-rc fixes along with
another GPIO fix for a section mismatch I have queued.

Minor: now that this driver has moved to drivers, I changed the subject
prefixes slightly.  They now read:

GPIO: OMAP: fix setting IRQWAKEN bits for OMAP4
GPIO: OMAP: add locking around calls to _set_gpio_triggering
