[Pavel Machek]

Hi!

USB gadget stops working for me on n900, if I merge

usb: gadget: bind UDC by name passed via usb_gadget_driver structure

patch.

    usb: gadget: bind UDC by name passed via usb_gadget_driver
    structure

    Introduce new 'udc_name' member to usb_gadget_driver structure.
        The 'udc_name' is a name of UDC that usb_gadget_driver should
	    be bound to. If udc_name is NULL, it will be bound to any
	        available UDC.

Patch is obvious enough... if there's someone who sets udc_name to
NULL. Who is supposed to do that?

(I have patch in my tree to make USB gadget work when it is not
modular).
