Subject: [PATCH v3 21/43] drm/malidp: Use GEM CMA object functions
Date: Fri,  5 Jun 2020 09:32:25 +0200	[thread overview]
Message-ID: <20200605073247.4057-22-tzimmermann@suse.de> (raw)
In-Reply-To: <20200605073247.4057-1-tzimmermann@suse.de>

Create GEM objects with drm_gem_cma_create_object_default_funcs(), which
allocates the object and sets CMA's default object functions. Corresponding
callbacks in struct drm_driver are cleared. No functional changes are made.

Driver and object-function instances use the same callback functions, with
the exception of vunmap. The implementation of vunmap is empty and left out
in CMA's default object functions.

v3:
	* convert to DRIVER_OPS macro in a separate patch
