Public bug reported: [Impact] On some lenovo notebooks, ucm files are not loaded and mic can't be used
[Fix] UCM was loaded based on cardlongname, but that can't cover all configs of the same model. Lenovo suggested to load ucm by the first 3 letters of /sys/devices/virtual/dmi/id/bios_version, so that all configs could use just one ucm.
