Thanks a lot.


What to do next then?

By the way, Bjorn, what's your opinion?
I'm ask because I don't know what to do next with this series.

As they belong to different system of Linux kernel,
the rest of patch (0002 ~ 0005) depend on the first one.

I think, merge the 0001-patch firstly, then wait it arrive at drm-misc, alsa branch.
Or, to do something else?
