There is no Kconfig symbol CONFIG_DRM_KMS_DMA_HELPER. The former CONFIG_DRM_KMS_CMA_HELPER was removed by commit 09717af7d13d ("drm: Remove CONFIG_DRM_KMS_CMA_HELPER option") before this driver was added, so the select does nothing. The driver already selects CONFIG_DRM_GEM_DMA_HELPER, which is what it needs. Remove the dead line.
