The encoder type was exposed to userspace by mistake, and AFAIU is unused by userspace, so it doesn't need to be specified.

The first encoder output on the SH-Mobile LCD Controller is a DPI parallel bus. However, at the time of introduction of the driver, no encoder or connector types were defined yet for the DPI parallel bus, hence the driver used the ones for LVDS instead. Adjust the types accordingly. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> --- drivers/gpu/drm/renesas/shmobile/shmob_drm_crtc.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-)
