From: Greg Kroah-Hartman
Date: Mon Apr 01 2019 - 13:30:27 EST
4.4-stable review patch. If anyone has any objections, please let me know.
From: Roger Quadros <rogerq@xxxxxx>
commit 04c080080855ce84dcd490a2e04805608a21085d upstream.
Pin state might have changed during suspend/resume while
our interrupts were disabled and if device doesn't support wakeup.
Scan for change during resume for such case.
