This is a false positive. USB_NET_RNDIS_HOST[1] selects USB_NET_CDCETHER[2], which makes USB_RTL8153_ECM[3] available.

Since USB_RTL8153_ECM is tristate with no prompt, users cannot directly set its value. And since it also has default y, the value is automatically selected to the highest value allowed by its dependencies, which USB_NET_CDCETHER && (USB_RTL8152 || USB_RTL8152=n) ends up selecting =m.
