From 7ccb4a53eb03c9196646ca0c2a97558313e886f1 Mon Sep 17 00:00:00 2001 From: Yuanhan Liu Date: Fri, 18 Mar 2011 07:37:35 +0000 Subject: [PATCH] drm/i915: Re-enable self-refresh A broken implementation of is_pot() prevented the detection of when a singular pipe was enabled. Eric Anholt pointed out the existence of is_power_of_2() so use that instead of our broken code!
