Off-by-one? "SSPx-Codec" would be 11 chars if you include null termination.

maybe better to do an explicit search that hard-code values?
This will actually not work if you have an additional FE for headset on 
GLK, or you are assuming a dependency on a patch added later in the 
series - not good.

does this work? You have the dai_name and cpu_dai_name pointing to the 
same string?

same here?
