[ Upstream commit fff8c10368e64e7f8960f149375c12ca5f3b30af ]

This code is really spurious.
It always returns an ERR_PTR, even when err is known to be 0 and calls
put_device() after a successful device_register() call.

It is likely that the return statement in the normal path is missing.
Add 'return rdev;' to fix it.
