Both the ds24xxx and ds2502 have a family_supported array which is local to the driver but was not marked as static. Mark this as static as both best practice and to allow both to be built in "allyesconfig" for example. Reviewed-by: Peng Fan <peng.fan@nxp.com> Signed-off-by: Tom Rini <trini@konsulko.com>
