Re: [PATCH v2 20/28] net: wan: Add framer framework support

+int framer_pm_runtime_get(struct framer *framer) +{

• int ret;
• if (!framer)

• return 0;
  

Can framer be a NULL pointer? This sort of test often covers up bugs. So either let it dereference the NULL pointer and opps, or return -EINVAL.
