[PATCH 2/2] mtd: ubi: use put_device() if device_register fail
Uhh, this is not obvious. Does device_register() really always return with a
reference held in all (error) cases?

Thanks,

if device_register() returned an error! Always use put_device()
to give up the reference initialized.(-- Please see the comment
for device_register() ). put_device() is able to handle those case
where it'll not return a reference.
