From: Gustavo Padovan <gustavo.padovan@xxxxxxxxxxxxxxx>
Due to the upcoming atomic modesetting feature we need to separate
some update functions into a check step that can fail and a commit
step that should, ideally, never fail.
The commit part can still fail, but that should be solved in another
upcoming patch.
