--- Comment #12 from Daniel Vetter <daniel at ffwll.ch> ---
Dropping just the config.mutex is dangerous, especially when we also call this
function from the disable/enable hooks where we always also hold the relevant
crtc->mutex.

I wonder a bit though who's hogging the kms lock - we chase an awful lot of
pointers to get at it, so if someone's corrupting this I expect we'd blow up.
And lockdep shouldn't be too happy about it either. Confusing.
