Hello,

As per the guidelines, Devices that are tried to register with
device_register or to add using device_add, must use put_device
on their failure path (not kfree). This series contains 3 patches
for updating such instances.

V2 <- V1
1. Removed patch [1] as it is part of another series [2] already.
