If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 0e93a9ad9a0f8eb22762156b8b9027ea932736bc Author: Dan Carpenter <dan.carpenter@xxxxxxxxxx> Date: Thu Nov 18 14:14:16 2021 +0300 drm/vc4: fix error code in vc4_create_object() [ Upstream commit 96c5f82ef0a145d3e56e5b26f2bf6dcd2ffeae1c ] The ->gem_create_object() functions are supposed to return NULL if there is an error. None of the callers expect error pointers so returing one will lead to an Oops. See drm_gem_vram_create(), for example. Fixes: c826a6e10644 ("drm/vc4: Add a BO cache.")
