Subject: [ 033/123] usb: gadget: tcm_usb_gadget: NULL terminate the FS descriptor list

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

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

From: Sebastian Andrzej Siewior <bigeasy@...utronix.de>

commit fad8deb274edcef1c8ca38946338f5f4f8126fe2 upstream.

The descriptor list for FS speed was not NULL terminated. This patch
fixes this.

While here one of the twe two bAlternateSetting assignments for the BOT
interface. Both assign 0, one is enough.
