If anyone has any objections, please let me know. ------------------ From: Igor Paunovic [ Upstream commit c83e3e806d4c115f1dad9ef756db4cd91448a262 ] dw_dp-rockchip.c calls drm_bridge_connector_init(), but ROCKCHIP_DW_DP does not select DRM_BRIDGE_CONNECTOR. A configuration with ROCKCHIP_DW_DP as the only enabled Rockchip output option fails to link: aarch64-linux-gnu-ld: drivers/gpu/drm/rockchip/dw_dp-rockchip.o: in function `dw_dp_rockchip_bind': dw_dp-rockchip.c:(.text+0x1d4): undefined reference to `drm_bridge_connector_init' Five other Rockchip encoder options that call drm_bridge_connector_init() (ROCKCHIP_ANALOGIX_DP, ROCKCHIP_CDN_DP, ROCKCHIP_DW_HDMI_QP, ROCKCHIP_LVDS, ROCKCHIP_RGB) already select it, which masks the gap in any configuration that enables one of them. ROCKCHIP_INNO_HDMI is covered through its DRM_INNO_HDMI core option. The same change was posted by Marius Dinu in March and dropped when the failure stopped reproducing in his build. The failure is configuration-dependent - any other enabled option that selects DRM_BRIDGE_CONNECTOR hides it - and it still reproduces on current drm-misc-next with the configuration described above. Select DRM_BRIDGE_CONNECTOR like the other users do.
