I'd have prefered to make all users of the reg pointer const in the hope
gcc can use that for optimization and to avoid stupid assignments via that
pointer but that turns out a significant problem on its own so I'm applying
your patch as is.
Please include a Signed-off-by: line (see Documentation/SubmittingPatches)
in future patches. If your patch was any more complex than this I'd not
have considered it without one.
