From 7ca51a3abf9e34232fcb3bff3c11befde73f8fd5 Mon Sep 17 00:00:00 2001 From: Jesse Barnes Date: Tue, 7 Jan 2014 13:50:49 -0800 Subject: [PATCH] drm/i915: check modeset state after a pipe_set_base if using fastboot Otherwise we won't check the state until the next DPMS transition, which may never happen.
