I don't see that branch in the swtpm tree:
address@hidden swtpm]$ git branch -a
* (HEAD detached at origin/master)
master
remotes/origin/HEAD -> origin/master
remotes/origin/coverity_scan
remotes/origin/master
remotes/origin/master.next
remotes/origin/tpm2-preview
remotes/origin/tpm2-preview.v2
(I need to untangle my system libtpms from that specific version to get it to
