[PATCH] drm: rcar-du: Replace drm_driver GEM ops with GEM object functions

[Laurent Pinchart]

The recommended way to specify GEM object functions is to provide a
drm_gem_object_funcs structure instance and set the GEM object to point
to it. The drm_cma_gem_create_object_default_funcs() function provided
by the GEM CMA helper does so when creating the GEM object, simplifying
the driver implementation. Switch to it, and remove the then unneeded
GEM-related opertions from rcar_du_driver.

Daniel, is this what you had in mind ?
