Subject[PATCH 4.4 024/131] extcon: usb-gpio: Dont miss event during suspend/resume
Date
4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Roger Quadros <rogerq@ti.com>

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.
