Like with panning and modesetting, and like with those, stick with simple drm_modeset_locking_all for the legacy path, and the full atomic dance for atomic drivers. This means a bit more boilerplate since setting up the atomic state machinery is rather verbose, but then this is shared code for 30+ drivers or so, so meh. After this patch there's only the LUT/cmap path which is still using drm_modeset_lock_all for an atomic driver. But Peter is already locking into reworking that, so I'll leave that code as-is for now. v2: Squash in patches from Maarten to unify all the various atomic paths into just one atomic update function for fbdev overall. On top do one s/restore_fbdev_mode/restore_fbdev_mode_atomic/ so that we have all-atomic callchains after the first check.
