Do I need to add Co-developed-by: Mickaël Salaün <mic@digikod.net>
and Signed-off-by: Mickaël Salaün <mic@digikod.net> or just
Co-developed-by: Mickaël Salaün <mic@digikod.net> ????
Cause Submiting patches article says:
https://www.kernel.org/doc/html/latest/process/submitting-patches.html
"...Since Co-developed-by: denotes authorship, every Co-developed-by:
must be immediately followed by a Signed-off-by: of the associated
co-author...."
Is this correct signing for this patch:
Co-developed-by: Mickaël Salaün <mic@digikod.net>
Signed-off-by: Mickaël Salaün <mic@digikod.net>
Signed-off-by: Konstantin Meskhidze <konstantin.meskhidze@huawei.com>
