Nice catch and looks correct. But please follow patch submission
guidelines from Documentation/SubmittingPatches. Here specifically:
- sob line missing
- Additional comments/questions should be below a line with just '---' so
that git apply-mbox drops it.
- Polish the commit message a bit. This wasn't too harmful since we
already look at connector, which has the same effect as the loop for any
non-cloned configs. Only when we have a cloned configuration is it
important to look at other connectors. Furthermore existing userspace
always changes dpms on all of them anyway.
Thanks, Daniel
