From 9ba29fcb76a559078491adffc74f66bf92b9dbea Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Mon, 9 Oct 2017 10:33:04 +1000 Subject: [PATCH] drm/amd/display: Use DRM new-style object iterators. Use the correct for_each_new/old_* iterators instead of for_each_* The following functions were considered: amdgpu_dm_find_first_crtc_matching_connector: use for_each_new - Old from_state_var flag was always choosing the new state amdgpu_dm_display_resume: use for_each_new - drm_atomic_helper_duplicate_state is called during suspend to cache the state - It sets 'state' within the state triplet to 'new_state' amdgpu_dm_commit_planes: use for_each_old - Called after the state was swapped (via atomic commit tail) amdgpu_dm_atomic_commit: use for_each_new - Called before the state is swapped amdgpu_dm_atomic_commit_tail: use for_each_old - Called after the state was swapped dm_update_crtcs_state: use for_each_new - Called before the state is swapped (via atomic check) amdgpu_dm_atomic_check: use for_each_new - Called before the state is swapped v2: Split out typo fixes to a new patch. v3: Say "functions considered" instead of "affected functions". The latter implies that changes are made to each.
