+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
