Subject: [PATCH v2] extcon: usb-gpio: Don't miss event during suspend/resume
Date: Fri, 8 Apr 2016 10:34:59 +0300 [thread overview]
Message-ID: <57075F23.8080703@ti.com> (raw)
In-Reply-To: <1459951299-20578-1-git-send-email-rogerq@ti.com>
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.
Signed-off-by: Roger Quadros <rogerq@ti.com>

v2:
- only check for state change during resume if device wakeup is not supported
