[PATCH 11/12] USB: ehci-omap: Try to get PHY even if not in PHY mode

From: Roger Quadros
Date: Tue Mar 12 2013 - 06:46:36 EST


Even when not in PHY mode, the USB device on the port (e.g. HUB)
might need resources like RESET which can be modelled as a PHY
device. So try to get the PHY device in any case.
