These have been scripted conversions then cleaned up by hand as there was no consistency to the formatting of the license headers in the common/ directory. Author information was also removed (it's in the git history) and so now the header format is consistently: ##/bin/bash # SPDX-License-Identifier: GPL-2.0(+) # Copyright (c) <date> <owner>.
