Hi,

It looks like you've sent a few patches editing the same file with 3?
chained together but the rest just own their own. This is a little
confusing trying to review. Typically you'd make a cover letter and then
chain them all together using git send-email.

Also, keep commit body lines under 75 chars. You should use this script
to catch things like this:

"$ ./scripts/checkpatch.pl --strict <patch>"

Thanks,

ET
