I added that patch to the alsa-lib-1.2.2 package, did a build and
installed it, unfortunately it does not help:

[hans at localhost ~]$ rpm -q alsa-lib
alsa-lib-1.2.2-1.hdg1.fc33.x86_64
[hans at localhost ~]$ alsaucm -c cht-bsw-rt5672 set _verb HiFi set _enadev Speaker
ALSA lib parser.c:1138:(verb_dev_list_add) error: unable to find device 'Speaker2'
...
