a=openpgp; fpr=8F88381DD5C873E4AE487DA5199BF1243632046A The commit b954fa6baaca ("drm/msm/dpu: Refactor rm iterator") removed zero-init of the hw_ctl array, but didn't change the error condition, that checked for hw_ctl[i] being NULL. At the same time because of the early returns in case of an error dpu_encoder_phys might be left with the resources assigned in the previous state. Rework assigning of hw_pp / hw_ctl to the dpu_encoder_phys in order to make sure they are always set correctly.
