From b6a88e4a804cf5a71159906e16df2c1fc7196f92 Mon Sep 17 00:00:00 2001 From: Daniele Ceraolo Spurio Date: Wed, 14 Feb 2018 11:18:25 -0800 Subject: [PATCH] drm/i915: Fix rsvd2 mask when out-fence is returned GENMASK_ULL wants the high bit of the mask first. The current value cancels the in-fence when an out-fence is returned.
