Subject: usb: gadget: udc: at91: do not rely on 'driver' argument
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=af9501f656d2250dbf04e48f77025b3783cc0505;p=openwrt%2Fstaging%2Fblogic.git

usb: gadget: udc: at91: do not rely on 'driver' argument

future patches will remove the extra 'driver'
argument to ->udc_stop(), in order to do that,
we must make sure that our UDC does not rely
on it first.
