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.
