There is a very strict rule saying on what line a SPDX header should be. Add an optional pedantic check for it. When the check is enabled, it will verify if the file has the SPDX header "at the first possible line in a file which can contain a comment", as stated at: Documentation/process/license-rules.rst Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org> --- scripts/spdxcheck.py | 34 +++++++++++++++++++++++++--------- 1 file changed, 25 insertions(+), 9 deletions(-)
