So it is, but this still looks like the wrong thing - it'll match on an
empty DAI name over an explicit match on the driver name which seems
like it's the wrong way round.

sorry, i don't know much about asoc, so i just trying to keep the original conditions and add the new one on it :)

the original one is:
if (dlc->dai_name && strcmp(dai->name, dlc->dai_name))
continue;

and i was trying to do something like:
if (dlc->dai_name && strcmp(dai->name, dlc->dai_name)
&& (!dai->driver->name || strcmp(dai->driver->name, dlc->dai_name)))
continue;

which is add an accept case for: dai driver name is valid and matches the dai name we are looking for...
