drm/panel: of_drm_find_panel() return a counted reference

2026-07-20T13:07:22+00:00

Callers of of_drm_find_panel() and drm_of_find_panel_or_bridge() receive a pointer with no reference held, creating a window where the panel device can be unregistered and freed between the lookup and first use (e.g., drm_panel_prepare()). Fix the lookup function by acquiring a reference with drm_panel_get() before returning, under panel_lock. Callers are now responsible for calling drm_panel_put() when they no longer need the pointer. For bridge drivers that immediately wrap the panel in a panel_bridge (which acquires its own reference), release the lookup reference right after the bridge creation call. For analogix-anx6345, which stores the panel for direct use, release the reference in the i2c remove path. For platform drivers using analogix_dp_core with a component lifecycle (exynos_dp, rockchip analogix_dp), release the lookup reference in the platform remove() function. The panel_bridge created during bind() holds a separate reference that devm cleanup releases after remove() returns. Also fix devm_drm_of_get_bridge() and drmm_of_get_bridge() in bridge/panel.c itself, update a second batch of drivers calling of_drm_find_panel() or drm_of_find_panel_or_bridge() to release the lookup reference after wrapping the panel in a bridge, and handle the cases where a panel is found but cannot be used, dropping the reference immediately in those paths.

Jump to the existing dev_put label when devm_request_irq() fails so drm_dev_put() and of_reserved_mem_device_release() run instead of returning early and leaking resources.

drm: include drm_print.h where needed

2025-10-31T08:34:52+00:00

There are a gazillion files that depend on drm_print.h being indirectly included via drm_buddy.h, drm_mm.h, or ttm/ttm_resource.h. In preparation for removing those includes, explicitly include drm_print.h where needed.
