I was planning take a look while I'm the road during the weekend.

Doug, from a quick look this revision still has a bunch of style
issues, most notably the alignment of function parameters and braces
around if / else.  See Documentation/CodingStyle in the kernel tree for
examples.

You might also want to run your patches through scripts/checkpatch.pl,
but take it with a grain of salt - it can be a bit too extreme at
times.  No need to post v3 with just style fixes, wait for more feedback.

Thanks,

                Ilya
