[Intel-gfx] [PATCH 2/4] drm/i915: Make *_crtc_mode_set work on new_config
Ander Conselvan de Oliveira
conselvan2 at gmail.com
Wed Oct 8 17:32:21 CEST 2014
From: Ander Conselvan de Oliveira <ander.conselvan.de.oliveira at intel.com>
This shouldn't change the behavior of those functions, since they are
called after the new_config is made effective and that points to the
current config. In a follow up patch, the mode set sequence will be
changed so this is called before disabling crtcs, and in that case
those functions should work on the staged config.
