[drm/i915] f029ee825c: BUG: looking up invalid subclass: 4294967295
by kernel test robot
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
git://anongit.freedesktop.org/drm-intel drm-intel-next-queued
commit f029ee825cdfc486b24ee67a3d4d0b2c05c9bee5
Author: Maarten Lankhorst <maarten.lankhorst(a)linux.intel.com>
AuthorDate: Wed Sep 23 16:29:37 2015 +0200
Commit: Daniel Vetter <daniel.vetter(a)ffwll.ch>
CommitDate: Mon Oct 19 11:38:11 2015 +0200
drm/i915: Only commit active planes when updating planes during reset.
In the next commit commit_plane will no longer check if the crtc is active.
To prevent issues with legacy page flips the check should be performed inside
update_primary_planes.
