From 77e012ac865037e5a227e69a294326b6ce93f9a4 Mon Sep 17 00:00:00 2001 From: Robert Jarzmik Date: Fri, 8 Jul 2016 22:09:07 +0200 Subject: [PATCH] usb: phy: generic: remove the vbus dependency As the last known user, ie. pxa27x_udc relying on calls to usb_gadget_xxx() was amended to use the phy notifier, remove a bit the USB stack adherence. Actually the driver still uses the gadget API for structures definition, but the implementation of USB gadget specific function usb_gadget_*() is not necessary anymore.
