This driver is the only user of of_drm_find_panel() which prints an error before doing probe deferral, yielding messages like this on boot, before eventually succeeding: [ 2.234271] [drm:rockchip_dp_probe] *ERROR* failed to find panel ... [ 4.797539] [drm:rockchip_dp_probe] *ERROR* failed to find panel ... Let's just drop the message.
