Hi Daniel,

2015-09-08 Daniel Vetter <daniel.vetter at ffwll.ch>:

> With the prep patches for i915 all kms drivers either have
> DRM_UNLOCKED on all their ioctls. Or the ioctl always directly returns
> with an invariant return value when in modeset mode. But that's only
> the case for i915 and radeon. The drm core ioctls are unfortunately
> too much a mess still to dare this.
> 
> Follow-up patches will remove DRM_UNLOCKED from all kms drivers to
> prove that this is indeed the case.
> 
> Also update the documentation.
