3.8.13.22 -stable review patch. If anyone has any objections, please let me know. ------------------ From: Gregory CLEMENT <gregory.clement@xxxxxxxxxxxxxxxxxx> commit d8eb6c653ef6b323d630de3c5685478469e248bc upstream. commit 511f3c5 (usb: gadget: udc-core: fix a regression during gadget driver unbinding) introduced a crash when DEBUG is enabled. The debug trace in the atmel_usba_stop function made the assumption that the driver pointer passed in parameter was not NULL, but since the commit above, such assumption was no longer always true. This commit now uses the driver pointer stored in udc which fixes this issue.
