UPSTREAM: driver core: Fix possible memory leak in device_link_add() ...
I got memory leak as follows:
unreferenced object 0xffff88801f0b2200 (size 64):

When device_register() returns an error, the name allocated in dev_set_name()
will be leaked, the put_device() should be used instead of kfree() to give up
the device reference, then the name will be freed in kobject_cleanup() and the
references of consumer and supplier will be decreased in device_link_release_fn().
