If a pin isn't marked as a wake source processing any interrupts is just going to destroy battery life. The APU may wake up from a hardware sleep state to process the interrupt but not return control to the OS.

Mask interrupt for all non-wake source pins at suspend. They'll be re-enabled at resume.

Not sure what is going on here, but it is queued for 6.6 and 4.14, but not for the kernels between them.

Ack, it should have been dropped from 4.14. Thanks!
