Re: [PATCH 3/3] drm/cma-helper: Pass GEM CMA object in public interfaces

Change all GEM CMA object functions that receive a GEM object of type struct drm_gem_object to expect an object of type struct drm_gem_cma_object instead.

This change reduces the number of upcasts from struct drm_gem_object by moving them into callers. The C compiler can now verify that the GEM CMA functions are called with the correct type.

For consistency, the patch also renames drm_gem_cma_free_object to drm_gem_cma_free. It further updates documentation for a number of functions.
