====================
net: fix device reference leaks

This series fixes a number of device reference leaks (and one of_node
leak) due to failure to drop the references taken by bus_find_device()
and friends.

Note that the final two patches have been compile tested only.

v2
 - hold reference to cpsw-phy-sel device while accessing private data as
   requested by David. Also update the commit message. (patch 1/4)
 - add linux-omap on CC where appropriate
