[PATCH 3.19.y-ckt 124/156] usb: gadget: m66592-udc: forever loop in set_feature()

[Kamal Mostafa]

3.19.8-ckt8 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Dan Carpenter <dan.carpenter at oracle.com>

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')
