From 48f34e10169dbb3dd7a19af64e328492b7f54af4 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Tue, 8 Oct 2013 12:25:42 +0200 Subject: [PATCH] drm/i915/dvo: call ->mode_set callback only when the port is running The ns2501 controller seems to need the dpll and dvo port to accept the timing update commands. Quick testing on my x30 here seems to indicate that other dvo controllers don't mind. So let's move the ->mode_set callback to a place where we have the port up and running already.
