This is a mistake that was not identified until now. Existing Intel DSDT tables use 'link' everywhere, and the MIPI spec will be updated to deprecate "mipi-sdw-master-N-subproperties" Fix to parse firmware information on existing devices. If we ever see a system with 'master-N-subproperties' I guess we'll have to try both.
