Hi,

Thanks for working on this, it'll be great to finally have this solved properly.

The compositor may use the same CRTC states, modes etc; whether or not
the commit actually ends up requiring a modeset depends entirely on
the exact contents of the commit. So I definitely wouldn't require
ALLOW_MODESET.
