Commit f89c696e7f63 ("drm/mediatek: mtk_dpi: Convert to bridge driver")
introduced the following build warning with W=1
drivers/gpu/drm/mediatek/mtk_dpi.c:530:39: warning: unused variable 'mtk_dpi_encoder_funcs' [-Wunused-const-variable]
static const struct drm_encoder_funcs mtk_dpi_encoder_funcs = {
This struct is and the 'mtk_dpi_encoder_destroy()' are not needed
anymore, so remove them.
