The atmel-hlcdc driver uses the default implementation for CMA functions. The DRM_GEM_CMA_DRIVER_OPS macro now sets these defaults in struct drm_driver. All remaining operations are provided by CMA GEM object functions.

When using DRM_GEM_CMA_DRIVER_OPS gem_prime_mmap is set to drm_gem_prime_mmap. Why is this the same as drm_gem_cma_prime_mmap?
Maybe this is all obvious when you know all the CMA stuff, but this puzzeled me.
