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.

drm/komeda: Convert logging in komeda_crtc.c to drm_* with drm_device parameter

2025-10-16T15:08:25+00:00

Replace all dev_err(), dev_warn(), dev_info() and DRM_ERROR/WARN/INFO() calls in drivers/gpu/drm/arm/display/komeda/komeda_crtc.c with the corresponding drm_err(), drm_warn(), and drm_info() helpers. The new drm_*() logging functions take a struct drm_device * as the first argument. This allows the DRM core to prefix log messages with the specific DRM device name and instance, which is essential for distinguishing logs when multiple GPUs or display controllers are present. This change aligns komeda with the DRM TODO item: "Convert logging to drm_* functions with drm_device parameter".

drm/arm/malidp: Switch to drm_atomic_get_new_crtc_state()

2025-10-06T11:59:09+00:00

The malidp atomic_check implementation uses the deprecated drm_atomic_get_existing_crtc_state() helper. This hook is called as part of the global atomic_check, thus before the states are swapped. The existing state thus points to the new state, and we can use drm_atomic_get_new_crtc_state() instead.

Allow it to be passed along into drm_helper_mode_fill_fb_struct() instead of doing yet another redundant lookup. Start by always passing in NULL and still doing the extra lookup.
