Subject: usb: gadget: m66592-udc: forever loop in set_feature()
From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>
commit 5feb5d2003499b1094d898c010a7604d7afddc4c upstream.
There is an "&&" vs "||" typo here so this loops 3000 times or if we get
unlucky it could loop forever.
Fixes: ceaa0a6eeadf ('usb: gadget: m66592-udc: add support for TEST_MODE')
