[RFC][PATCH] (1/3) unchecked requst_region's in drivers/net

[Steven Walter]

Alright, here are the obvious patches, which I'm sending seperately as
Alan requested.  The next message will have those patches which are
approved by their respective maintainers, and the last those patches for
drivers whose maintainers didn't respond.  Those will likely require
more scrutiny.

Andrew, I have (hopefully) addressed all the issues you brought up in
the patches.
