drm/msm/hdmi_phy: fix runtime PM cleanup on probe failure

2026-09-14T23:09:28Z

msm_hdmi_phy_probe() enables runtime PM before enabling the PHY resources and initializing the PLL, but failures from either operation return without calling the matching pm_runtime_disable(). The remove path disables runtime PM, but it is not called when probe fails. As a result, runtime PM remains enabled after an unsuccessful probe. Route failures after pm_runtime_enable() through a common error path and disable runtime PM before returning. This issue was found by manual code inspection.

drm/msm: hdmi: Switch to atomic_create_state

2026-06-22T09:24:48Z

The drm_bridge_funcs.atomic_reset callback and its drm_atomic_helper_bridge_reset() helper are deprecated. Switch to the atomic_create_state callback and its drm_atomic_helper_bridge_create_state() counterpart.

drm/msm/hdmi: switch to of_drm_get_bridge_by_endpoint()

2026-05-19T08:57:25Z

This driver calls drm_of_find_panel_or_bridge() with a NULL pointer in the @panel parameter, thus using a reduced feature set of that function. Replace this call with the simpler of_drm_get_bridge_by_endpoint(). Since of_drm_get_bridge_by_endpoint() increases the refcount of the returned bridge, ensure it is put on removal.

drm: Rename struct drm_atomic_state to drm_atomic_commit

2026-05-04T04:05:04Z

The KMS framework uses two slightly different definitions for the state concept. For a given object (plane, CRTC, encoder, etc., so drm_$OBJECT_state), the state is the entire state of that object. However, at the device level, drm_atomic_state refers to a state update for a limited number of objects. Thus, drm_atomic_state isn't the entire device state, but only the full state of some objects in that device. This has been an endless source of confusion and thus bugs. We can rename the drm_atomic_state structure to drm_atomic_commit to make it less confusing. This patch was created using: rg -l drm_atomic_state | \ xargs sed -i 's/drm_atomic_state/drm_atomic_commit/g; s/drm_atomic_commit_helper/drm_atomic_state_helper/g' mv drivers/gpu/drm/tests/drm_atomic_state_test.c drivers/gpu/drm/tests/drm_atomic_commit_test.c Acked-by: Simona Vetter Acked-by: Thomas Zimmermann Acked-by: Jani Nikula Reviewed-by: Luca Ceresoli Tested-by: Luca Ceresoli Signed-off-by: Maxime Ripard Signed-off-by: Dave Airlie Link: https://patch.msgid.link/20260427-drm-drm-atomic-update-v4-1-c0e713bfdf25@kernel.org
