This patch looks good.

It is not a big issue, but have it in mind for the future. When fixing issues
reported by checkpatch, it is nice to paste the output warning of checkpatch
in the commit message.

Look at this example:
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/?id=e7a142aaa09fa5db015fd176d6943f888665829f

Thanks,
