Hi Philip

The new one is not a PNP ID.  Those only have 3 letters.
They have switched over to using an ACPI ID - which is the other thing you
are allowed to put in _HID in ACPI.

Good to see they are using a valid format at least and hopefully Bosch
have indeed allocated that code to this device.  So rare case of a correct
update.

FWIW BMI was the PNP ID of the Benson medical instruments company.


So with a minor commit text update to reflect that I'll be happy to pick
this one up.

Thanks

Jonathan
