From 5751d0f6c54f32ee19a55d30b1255aa8ab30390e Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Tue, 5 Jan 2016 17:54:07 +0100 Subject: [PATCH] drm/i915: Tune down rpm wakelock debug checks They're causing massive amounts of dmesg noise and hence CI noise all over the place. Enabling them for a bit was good enough to refresh our task list of what's still needed to enable rpm by default. To make sure we're not forgetting to make this noisy again add a FIXME comment.
