Thanks Jan, I was able to take these 2 mails and merge them together to a single patch.
I will send the result for review in a bit. Next time please learn some git/linux kernel developer basics. It will help make this more smooth inthe future. THe code changes you made were great and I hope to see more in the future. :) Some tips: - Use 'git rebase -i', and the fixup/squash command to merge two or more commits. Also, there you should add the summary as you did in your mail in the git commit message. - Use 'git format-patch -o patch-dir -v2 <batch-base-commit-id>' to create your patch. - Use './scripts/checkpatch.pl patch-dir/<patch-name>.patch' to check your patch before you send it. If any issues use 'git rebase' or 'git commit --amend' to fix up the checkpatch issues then test and create a new patch. - Use './scripts/get-maintainers.pl' with 'git send-email' like this below.
