From: Colin Ian King <redacted>
The pointer of_node is being initialized with a value that is never
read and it is being updated later with a new value inside a do-while
loop. The initialization is redundant and can be removed and the
pointer dev is no longer required and can be removed too.
Addresses-Coverity: ("Unused value")
