Subject: [PATCH] drm/vc4: fix error code in vc4_create_object()
Date: Thu, 18 Nov 2021 14:14:16 +0300 [thread overview]
Message-ID: <20211118111416.GC1147@kili> (raw)
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.")
