Subject: [PATCH] fix-gta01-pmu-irq-edge-lost-on-resume.patch

GTA01 -only

Restore power button functionality after resume operation

Per Werner's suggestion, run the PMU interrupt handler immediately after resume
to clear/handle any pending interrupts from that device.  This appears to
resolve the  dead-powerbutton-after-resume problem.  This is not well-tested;
need feedback to see if there are any side-effects or other problems.

From BZ 1313
