This is a note to let you know that I've just added the patch titled drm/vc4: fix error code in vc4_create_object() to the 4.9-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: drm-vc4-fix-error-code-in-vc4_create_object.patch and it can be found in the queue-4.9 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit eec345e3779d41b7b467588a8046ad9a8bca761e 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.")
