Subject: usb: dwc3: ep0: add a default case for SetFeature command
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=ecb07797ffc1c2aaa2e58d1ba1b5deea44ea5b9e;p=deliverable%2Flinux.git

usb: dwc3: ep0: add a default case for SetFeature command

Without this default case returning an error,
thus replying with a stall, we would fail
USB30CV TD 9.11 Bad Feature test case.
