[PATCH 2/5] drm/amd/display: Move iteration out of dm_update_crtcs
sunpeng.li at amd.com
sunpeng.li at amd.com
Tue Dec 18 15:26:13 UTC 2018
From: Leo Li <sunpeng.li at amd.com>
In preparation of implementing the CRTC atomic_check helper,
dm_update_crtcs need to operate on single instances.
Move iteration of plane states into atomic_check.
No functional change is intended.
