[PATCH v2 1/6] drm/bridge: dw-hdmi: convert to of_drm_find_and_get_bridge()

From: Luca Ceresoli
Date: Fri Jan 09 2026 - 05:12:36 EST


of_drm_find_bridge() is deprecated. Move to its replacement
of_drm_find_and_get_bridge() which gets a bridge reference, and ensure it
is put when done by using the drm_bridge::next_bridge pointer.
