Subject: [PATCH] ALSA: hda: Add driver blacklist
Git-commit: 3c6fd1f07ed03a04debbb9a9d782205f1ef5e2ab
Patch-mainline: v5.7-rc1
References: bsc#1051510

The recent AMD platform exposes an HD-audio bus but without any actual
codecs, which is internally tied with a USB-audio device, supposedly.
It results in "no codecs" error of HD-audio bus driver, and it's
nothing but a waste of resources.

This patch introduces a static blacklist table for skipping such a
known bogus PCI SSID entry.  As of writing this patch, the known SSIDs
Are: 
* 1043:874f - ASUS ROG Zenith II / Strix
* 1462:cb59 - MSI TRX40 Creator
* 1462:cb60 - MSI TRX40
