[PATCH v1 8/8] usb: otg: palmas-usb: fix cold plug issue

From: Kishon Vijay Abraham I
Date: Thu Jan 24 2013 - 22:12:55 EST


if the cable is connected even before the palmas-usb is loaded, the
cable connect detection event will be missed. It's fixed here by checking
for VBUS line states when palmas-usb is loaded.
