nouveau_connector.c:535 nouveau_connector_set_property() warn: variable derefe

Hi Ben,

FYI, a pretty old smatch warning:

drivers/gpu/drm/nouveau/nouveau_connector.c:535 nouveau_connector_set_property() warn: variable dereferenced before check 'nv_encoder' (see line 413)

vim +535 drivers/gpu/drm/nouveau/nouveau_connector.c
412 struct nouveau_encoder *nv_encoder = nv_connector->detected_encoder;
413 struct drm_encoder *encoder = to_drm_encoder(nv_encoder);
...
534

536 return get_slave_funcs(encoder)->set_property(
537 encoder, connector, property, value);
538
539 return -EINVAL;
540 }
