Subject: [16/21] usb: gadget: zero: fix bug in loopback autoresume handling

2.6.32-longterm review patch.  If anyone has any objections, please let me know.

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

From: Timo Juhani Lindfors <timo.lindfors@....fi>

commit 683da59d7b8ae04891636d4b59893cd4e9b0b7e5 upstream.

ab943a2e125b (USB: gadget: gadget zero uses new suspend/resume hooks)
introduced a copy-paste error where f_loopback.c writes to a variable
declared in f_sourcesink.c. This prevents one from creating gadgets
that only have a loopback function.
