I tried applying your patch, but it failed:

When you have resolved this problem, run "git am --continue".
If you prefer to skip this patch, run "git am --skip" instead.
To restore the original branch and stop patching, run "git am --abort".

It seems the patch is corrupted.

./scripts/checkpatch.pl shows several issues as well.

Please fix these problems and submit a v2 using 'git send-mail'.

Thanks
