The 'speed' variable is of the unsigned int type so the type qualifier is
supposed to be "%u" here.

BTW I don't know whether it's ok to have an empty description in the
patches for the networking subsystem, but the kernel maintainers
mainly request to add at least some text with the change justification
especially seeing the submitting-patches.rst doc says the description
is mandatory.
