Por lo tanto, el caso común para cpsw_ethtool_begin es devolver 1. Eso lleva a llamadas inconsistentes a pm_runtime_put en la cadena de llamadas, de modo que pm_runtime_put se llama una vez de más y, como resultado, deja suspendido el cpsw dev. El cpsw dev suspendido lleva a una violación de acceso más adelante por diferentes partes del controlador cpsw.
