From: "Leo (Sunpeng) Li" <sunpeng.li@xxxxxxx> Use the correct for_each_new/old_* iterators instead of for_each_* List of affected functions: 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.
