From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
Pointer of_node is initialized with a value that is never read, of_node
is later updated with a new value instead, hence the initialization is
redundant and can be removed. Also remove unused pointer dev and
remove an empty line.
Cleans up clang warnings:
drivers/net/phy/micrel.c:393:28: warning: Value stored to 'of_node'
during its initialization is never read
drivers/net/phy/micrel.c:532:28: warning: Value stored to 'of_node'
during its initialization is never read
