Signed-off-by: Andrzej Hajda a.hajda@samsung.com --- Hi,
This patch is based on the latest drm-next. I have removed all dumb implementations except for qxl_display.c, which is not entirely dumb - it contains log and TODO comments.
Changes seems to be quite obvious so I have put everything into single patch.

Hi,
This patch is based on the latest drm-next. I have removed all dumb implementations except for qxl_display.c, which is not entirely dumb - it contains log and TODO comments.
Changes seems to be quite obvious so I have put everything into single patch.
Can you please also update the drm DocBook and add a small comment stating that this callback is now optional? Looks good to me otherwise.
Thanks, Daniel

Hi David,
Gently ping.
I've just sent a pull request with this patch. I've merged it to topic/core-stuff in drm-intel git, so it should get taken care of eventually. -Daniel

Hi Dave,
Could you pick up this patch? It touches drm core and different drm drivers so I guess your repo is the best place for it.

Many drm connectors do not need mode validation. The patch makes this callback optional and removes dumb implementations.
