Subject[PATCH 3.16 148/357] usb: dwc2/gadget: avoid disabling ep0
Date
3.16-stable review patch.  If anyone has any objections, please let me know.

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

From: Robert Baldyga <r.baldyga@samsung.com>

commit 604eac3c0c69e98f2fd0133305f9e777418f1d3b upstream.

Endpoint 0 should not be disabled, so we start loop counter from number 1.
