commit 42d95d1b3a9c649bf5ee881fee5938e00126479a upstream. The meaning of the 'imply' keyword has changed recently, and neither the old meaning (select the symbol if its dependencies are met) nor the new meaning (enable it by default, but let the user set any other setting) is what we want here. Work around this by adding two more Kconfig options that lead to the correct behavior: if DRM_RCAR_USE_CMM and DRM_RCAR_USE_LVDS are enabled, that portion of the driver becomes usable, and no configuration results in a link error. This avoids a link failure: arm-linux-gnueabi-ld: drivers/gpu/drm/rcar-du/rcar_du_crtc.o: in function `rcar_du_crtc_atomic_begin': rcar_du_crtc.c:(.text+0x1444): undefined reference to `rcar_cmm_setup' arm-linux-gnueabi-ld: drivers/gpu/drm/rcar-du/rcar_du_crtc.o: in function `rcar_du_crtc_atomic_enable': rcar_du_crtc.c:(.text+0x14d4): undefined reference to `rcar_cmm_enable' arm-linux-gnueabi-ld: rcar_du_crtc.c:(.text+0x1548): undefined reference to `rcar_cmm_setup' arm-linux-gnueabi-ld: drivers/gpu/drm/rcar-du/rcar_du_crtc.o: in function `rcar_du_crtc_atomic_disable': rcar_du_crtc.c:(.text+0x18b8): undefined reference to `rcar_cmm_disable' arm-linux-gnueabi-ld: drivers/gpu/drm/rcar-du/rcar_du_kms.o: in function `rcar_du_modeset_init': Link: https://lore.kernel.org/all/20200417155553.675905-5-arnd@arndb.de/ Signed-off-by: Arnd Bergmann <arnd@arndb.de> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Randy Dunlap <rdunlap@infradead.org> Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Cc: Dan Carpenter <dan.carpenter@linaro.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
