  Indicating this is actually a firmware problem.
  
  Verified this has been fixed at least in upstream linux-firmware commit
  29a536a02cadb75b84c6c0b5d7af22d34d278563, firmware release version
  21.10.0.6. With that firmware blob placed under /lib/firmware/intel and
  a cold boot, dmesg gives updated revision and device pairing works as
  expected:
  
-   Firmware revision 0.1 build 184 week 15 2019
+   Firmware revision 0.1 build 184 week 15 2019
