etc/scripts/set_copyright_year.sh outputs only one issue at a time #451
Description
When using ./etc/scripts/set_copyright_year.sh --check, the script currently only outputs the first problem with the copyright, which is a little bit inefficient.
Instead, it should output the complete list of copyright issues.
Furthermore, I suspect it's only running in the sdk directory, when touching it, please also check that it's configured to run on the complete repository.
