From 4efd631e2f48536221a8512e83785484d73bb8ea Mon Sep 17 00:00:00 2001 From: Thomas Zimmermann <tzimmermann@suse.de> Date: Tue, 31 Jul 2018 08:31:28 +0200 Subject: drm/cirrus: Replace ttm_bo_unref with ttm_bo_put The function ttm_bo_put releases a reference to a TTM buffer object. The function's name is more aligned to the Linux kernel convention of naming ref-counting function _get and _put. A call to ttm_bo_unref takes the address of the TTM BO object's pointer and clears the pointer's value to NULL. This is not necessary in most cases and sometimes even worked around by the calling code. A call to ttm_bo_put only releases the reference without clearing the pointer. The current behaviour of cleaning the pointer is kept in the calling code, but should be removed if not required in a later patch.
