Ville Syrjälä aeec766133 drm/i915: Don't oops in dumb_create ioctl if we have no crtcs ... Make sure we have a crtc before probing its primary plane's max stride. Initially I thought we can't get this far without crtcs, but looks like we can via the dumb_create ioctl. Not sure if we shouldn't disable dumb buffer support entirely when we have no crtcs, but that would require some amount of work as the only thing currently being checked is dev->driver->dumb_create which we'd have to convert to some device specific dynamic thing.
