The fsl-dcu driver uses the gem_cma_helper code, but does noto enforce enabling this through Kconfig: arm-linux-gnueabi-ld: drivers/gpu/drm/fsl-dcu/fsl_dcu_drm_drv.o:(.rodata+0x32c): undefined reference to `drm_gem_cma_prime_import_sg_table' arm-linux-gnueabi-ld: drivers/gpu/drm/fsl-dcu/fsl_dcu_drm_drv.o:(.rodata+0x334): undefined reference to `drm_gem_cma_dumb_create' arm-linux-gnueabi-ld: drivers/gpu/drm/fsl-dcu/fsl_dcu_drm_plane.o: in function `fsl_dcu_drm_plane_atomic_update': fsl_dcu_drm_plane.c:(.text+0x144): undefined reference to `drm_fb_cma_get_gem_obj' Add the same 'select' that is used in other such drivers.
