usb: gadget: fix a bug and a WARN_ON in dummy-hcd
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.
