From: Dave Airlie <airlied@xxxxxxxxxx>
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.
[airlied: squashed with my hacks]
