Subject: usb: gadget: udc: dummy: do not rely on 'driver' argument
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=96a5361aab7a89cf80cb4fe03966f55f00b0d91f;p=openwrt%2Fstaging%2Fblogic.git

usb: gadget: udc: dummy: 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.
