PS4, Line 53: 				return strdup(known_guids->alias);
> Typo? This should be `known_guid->alias`, otherwise the `coreboot` guid is always returned here

Definitely, thank you.  Updated these functions before uploading and introduced bugs.

PS4, Line 73: 			*guid = known_guids->guid;
> As above, I think this should be `known_guid->alias`

Done
