[PATCH 5.4 068/321] drm/fsl-dcu: Use GEM CMA object functions

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



5.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Thomas Zimmermann <tzimmermann@xxxxxxx>

[ Upstream commit 929027087f527ef1d9e906e4ebeca7eb3a36042e ]

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
