Merge branch 'rid-w-1-warnings-in-ethernet'

Lee Jones says:

====================
Rid W=1 warnings in Ethernet

This set is part of a larger effort attempting to clean-up W=1
kernel builds, which are currently overwhelmingly riddled with
niggly little warnings.

v2:
 - Squashed IBM patches
 - Fixed real issue in SMSC
 - Added Andrew's Reviewed-by tags on remainder
====================
