Subject: usb: gadget: udc: net2280: do not rely on 'driver' argument
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=bfd0ed576dbf9cc71af7dbe42841fc9246524961;p=deliverable%2Flinux.git

usb: gadget: udc: net2280: 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.
