Revision 836855100b87b4dd7a82546131779dc255c18b67 authored by Cezary Rojewski on 19 May 2023, 20:17:09 UTC, committed by Mark Brown on 22 May 2023, 10:18:24 UTC
Configurations with multiple codecs attached to the platform are supported but only if each from the set is different. Add new field representing the 'Unique ID' so that codecs that share Vendor and Part IDs can be differentiated and thus enabling support for such configurations.
