With the original implementation only the debugfs files are only created for the first codec, other codecs loaded later would fail to create the debugfs files (since they are already exist). Furthermore in this situation any of the codecs has been removed, would cause the debugfs entries to disappear, regardless if the codec, which created them are still loaded (the one which loaded first).

There's way more problems than this with multiple CODECs and multiple cards - DAPM can't really cope at all, and the split between CODECs and cards isn't as clear as would be desirable. Looking into this is one of my big tasks for the rest of the year. With this particular problem I suspect the fix will fall out of the other reorganisations required to make the rest of the system work.
codec->debugfs_codec_root = debugfs_create_dir(codec->name,debugfs_root);
I don't think the CODEC name is what we want to use here, one of the common cases is going to be to have two or more mono DACs or speaker drivers in the system, normally of the same type and therefore with the same name set here. A dev_name() is going to be required as well, munged in with the CODEC name for usability.
