The "prefix" can be defined in DAI link node or it can be specified as part of the component node itself. Currently "sound-name-prefix" defined in a component is not taking effect. Actually the property is not getting parsed. It can be fixed by parsing "sound-name-prefix" property whenever "prefix" is missing in DAI link Codec node.

It is not obvious how the patch fixes the problem described. I guess now map->name_prefix is NULL on some level and overrides prefix found earlier?

If map->name_prefix is NULL (which is the prefix defined for Codec DAI component in a DAI link), then go ahead and check if "sound-name-prefix" is provided under component device node itself.
