checkpatch.pl is warning as below:

    WARNING: Reported-by: should be immediately followed by Link: with a URL to the report
    #20:
    Reported-by: Naresh Kamboju <naresh.kamboju@...aro.org>
    Signed-off-by: Anders Roxell <anders.roxell@...aro.org>

The reason for the warning can be found from commit d7f1d71e5ef6 ("checkpatch:
warn when Reported-by: is not followed by Link:")'s commit message.  Do you
have a link to put here?  I guess the report was made inside Linaro, so might
have no publicly available link.  Maybe better to add some notes or some funny
tag like "Link: N/A # no publicly-available link of the report" for convincing
the tool, but I don't think this should be a blocker for this patch.
