[PATCH 07/14] drm/mgag200: Replace simple-KMS with regular atomic helpers

[Thomas Zimmermann]

(cc'ing dri-devel, Jocelyn and Sam)

Hi Phil,

I've put dri-devel into cc, which is the developer's mailing list. It's 
the first time I hear about this bug.

You cannot really revert it, as it's too old already. But could you 
please try the latest developer tree from

   git://anongit.freedesktop.org/drm/drm-tip

The branch is drm-tip. Maybe the bug has been fixed meanwhile. If this 
also doesn't work, we can take a closer look at the changes.

Best regards
Thomas
