Was this commit tested? Or was it only tested as a part of the patchset, after this code has been rewritten by the subsequent patches? I will replace this with crtc_state->crtc, but generatlly this looks bad. > num_lm = dpu_rm_get_assigned_resources(&dpu_kms->rm, global_state, > - drm_enc->base.id, DPU_HW_BLK_LM, hw_lm, ARRAY_SIZE(hw_lm));
