I just updated SubmitAPatch to mention running scripts/checkpatch.pl before submitting patches: http://wiki.qemu.org/Contribute/SubmitAPatch
"Follow the coding style and run scripts/checkpatch.pl <patchfile> before submitting" Checkpatch.pl makes it easy to follow the coding style and eliminates the "please add a curly brace and resend the patch" hassle :). Stefan
