Very odd formatting.

I'm confused. Have you read kernel patch submissions? Look at how they are formatted. The documentation in the kernel tree should help you out a lot here.
Also, this is not v1, it has changed from the previous version. Always describe, in the correct way, the changes from previous submissions.

Always run your patches through scripts/checkpatch.pl so you do you not get grumpy maintainers telling you to use scripts/checkpatch.pl
Stop. Take some time. Redo the patch in another day or so, and then resend it later, _AFTER_ you have addressed the issues. Don't rush, there is no race here.
