    Subject[PATCH 5.10 058/121] drm/vc4: fix error code in vc4_create_object()
    Date
    From: Dan Carpenter <dan.carpenter@oracle.com>

    [ 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.")
