OK so some automatic scripts were fixing the SPDX tags in the mainline branch while we were patching other stuff, and yeah it is more correct to have "GPL-2.0-only" rather than "GPL-2.0" so let's conform to what is already upstream so we don't end up getting the wrong license on the merged result later.
