Yang Yingliang 5d03c2911c siox: fix possible memory leak in siox_device_add()
[ Upstream commit 6e63153db5 ]

If device_register() returns error in siox_device_add(),
the name allocated by dev_set_name() need be freed. As
comment of device_register() says, it should use put_device()
to give up the reference in the error path. So fix this
by calling put_device(), then the name can be freed in
kobject_cleanup(), and sdevice is freed in siox_device_release(),
set it to null in error path.
