Sorry, I should have mentioned this for v1 already, but better late than never: We need to replace this patch with a proper header update later (via the scripts/update-linux-headers.sh script) - so in case you respin, please mark it with NOTFORMERGE or PLACEHOLDER or something similar in the subject, and mention the kernel version in the description that will likely contain the update.
