Subject: [PATCH 2/3] usb: gadget: udc: atmel: fix uninitialized read in debug
 printk

Fixed commit moved the assignment of 'req', but did not update a
reference in the DBG() call. Use the argument as it was renamed.

Fixes: 5fb694f96e7c ("usb: gadget: udc: atmel: fix possible oops when unloading module")
