The patch below fixes various nits (mostly adding locking) in most of the
smbus controller drivers we have in the tree. It should apply to both HEAD
and RELENG_6 with the exception that the intpm(4) driver will require the
style fixes to be applied to RELENG_6 first. If you aren't using intpm and
want to test on RELENG_6, you can just ignore that part of the patch. Please
test, thanks.
