Subject: [ 02/56] usb: gadget: initialize the strings in tcm_usb_gadget properly
3.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sebastian Andrzej Siewior <bigeasy@...utronix.de>
commit 18786da4853017d983ff6911648543ca617c12d1 upstream.
I have no idea what I've been thinking while I was doing this in the first
place. Now the strings are initialized properly and reported by lsusb.
