Subject: drm/i2c: tda998x: move mode_valid() to bridge
Git-commit: b073a70ecd37bc6e7c25a47315cd8d65e7b313fd
Patch-mainline: v4.19-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

Move the mode_valid() implementation to the bridge instead of the
connector, as we're checking the bridge's capabilities.
