Merge branch 'bcm4908_enet-post-review-fixes' 

Rafał Miłecki says:

====================
bcm4908_enet: post-review fixes

V2 of my BCM4908 Ethernet patchset was applied to the net-next.git and
it was later that is received some extra reviews. I'm sending patches
that handle pointed out issues.

David: earler I missed that V2 was applied and I sent V3 and V4 of my
inital patchset. Sorry for that. I think it's the best to ignore V3 and
V4 I sent and proceed with this fixes patchset instead.
