HEAD is a revision, not a branch and the fetcher became a bit more
picky about that difference. Your local tree must have HEAD on some
branch which would usually be master so setting branch=master is likely
correct, or don't set that parameter at all? master isn't just a remote
thing.

The piece which says "use the HEAD revision" is the SRCREV =
"${AUTOREV}" line.
