I have a driver compiled with Kernel/DRM CONFIG_DRM_GEM_CMA_HELPER=y on Kernel Ver-5.15.0.131. But on Kernel Ver-6.1.55, I cannot find CONFIG_DRM_GEM_CMA_HELPER. The file drm_gem_cma_helper.h is not in the Kernel. Did I miss anything? Also my driver needs drm_ioctl. drm_ioctl.h is in inclde/drm/. But

error: ‘drm_ioctl’ undeclared here

Which CONFIG_DRM_? generates code with drm_ioctl support?
