There is a pretty obvious typo in there:

With that it works and I don't see the flickering in a short test. I
will do more testing, but maybe Dan can test, too.

After fixing the typo the patch is working for me, also. dmesg is also
clean. I will continue running the patched kernel. If I see any
issues, I will report back here.

Thanks for fixing that stupid typo. I've just send out an updated 
version to the mailing list with everybody in CC.

Please review and/or comment further.

Regards,
Christian.
