Hi, Angelo: AngeloGioacchino Del Regno <angelogioacchino.delregno@collabora.com> 於 2025年2月17日 週一 下午11:49寫道： > > Move the vendor and product strings to the appropriate entries > of struct drm_bridge and use that in mtk_hdmi_setup_spd_infoframe > instead of having the same as function parameters. > > While at it, also beautify the strings, setting them to read > "MediaTek On-Chip HDMI". Applied to mediatek-drm-next [1], thanks.
