Sorry for not spotting this before, but per section 11 of
Documentation/process/submitting-patches.rst the tag part should read:
Tested-by: Fabien Dessenne <fabien.dessenne@xxxxxx>
Signed-off-by: Bjorn Andersson <bjorn.andersson@xxxxxxxxxx>
[elder@xxxxxxxxxx: minor comment edits]
Signed-off-by: Alex Elder <elder@xxxxxxxxxx>
I.e. as you're sending the email you must be the last one certifying the
origin of the patch.
Regards,
Bjorn
