Please find attached the relevant logs. It really seems that g_nokia is
probed twice, with all the gadgets in it created two times. I am
starting to suspect 855ed04a3758b205e84b269f92d26ab36ed8e2f7 ("usb:
gadget: udc-core: independent registration of gadgets and gadget
drivers") has something to do with the problem, though reverting it
resulted in g_nokia not being probed at all :)
