Subject: [PATCH v2 3/6] drm/mediatek: mtk_dpi: Switch to devm_drm_of_get_bridge()
Date:   Wed, 19 Jul 2023 09:50:53 +0200

Function drm_of_find_panel_or_bridge() is marked as deprecated: since
the usage of that in this driver exactly corresponds to the new function
devm_drm_of_get_bridge(), switch to it.
