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.
