Subject: [PATCH] drm/vc4: fix error code in vc4_create_object()
Git-commit: 96c5f82ef0a145d3e56e5b26f2bf6dcd2ffeae1c
Patch-mainline: v5.16-rc3
References: git-fixes

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.")
