From 2465ff6217f1b63e194cfd57018fa42abe7fcdf0 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Thu, 18 Jun 2015 09:58:55 +0200 Subject: drm/atomic: Extract needs_modeset function We use the same check already in the atomic core, so might as well make this official. And it's also reused in e.g. i915. Motivated by Maarten's idea to extract a connector_changed state out of mode_changed.
