Merge branch 'net-of_node_put'

Peter Chen says:

====================
add missing of_node_put after calling of_parse_phandle

This patch set fixes missing of_node_put issue at ethernet driver.
of_node_put needs to be called when the device node which is got
from of_parse_phandle has finished using.

The compilation test has passed by using allmodconfig for drivers/net/ethernet.

Changes for v2:
- If the device node is local variable, it can be put in the same function.
- If the device node will be used the whole driver life cycle,
  it should be put (call of_node_put) at driver's remove.
  Patch [4, 5, 9, 14, 15/15]
- Fix the issue that the node still be used at error patch [6/15]
- Add acked for patch [11,12/15]
