Subject: usb: dwc3: gadget: fix endpoint renaming
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e901aa159dac9988c9961c31c01730effe8f5c22;p=linux-beck.git

usb: dwc3: gadget: fix endpoint renaming

We were exitting the function before actually
renaming anything. While at that, also always leave
control endpoint un-renamed.
