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.
