+Subject: usb: chipidea: udc: check request status before setting device address
+
+From: Xu Yang <xu.yang_2@nxp.com>
+
+commit b24346a240b36cfc4df194d145463874985aa29b upstream.
+
+The complete() function may be called even though request is not
+completed. In this case, it's necessary to check request status so
+as not to set device address wrongly.
+
+Fixes: 10775eb17bee ("usb: chipidea: udc: update gadget states according to ch9")
