+Subject: usb: gadget: fix a bug and a WARN_ON in dummy-hcd
+
+From: Alan Stern <stern@rowland.harvard.edu>
+
+commit 5f5610f69be3a925b1f79af27150bb7377bc9ad6 upstream.
+
+This patch fixes a NULL pointer dereference and a WARN_ON in
+dummy-hcd.  These things were the result of moving to the UDC core
+framework, and possibly of changes to that framework.
+
+Now unloading a gadget driver causes the UDC to be stopped after the
+gadget driver is unbound, not before.  Therefore the "driver" argument
+to dummy_udc_stop() can be NULL, so we must not try to print the
+driver's name without checking first.
+
+Also, the UDC framework automatically unregisters the gadget when the
+UDC is deleted.  Therefore a sysfs attribute file attached to the
+gadget must be removed before the UDC is deleted, not after.
