One of the framework responsibilities is to ensure that the enumerated DPCMs are valid i.e.: a valid BE is connected to a valid FE DAI. While the are checks in soc-core.c and soc-pcm.c that verify this, a component driver may attempt to workaround this by loading an invalid graph through the topology file. Be strict and fail topology loading when invalid graph is encountered.
