UTSA-2026-013032 advisory.

    In the Linux kernel, the following vulnerability has been resolved:

    devlink: report devlink_port_type_warn source device

    devlink_port_type_warn is scheduled for port devlink and warning
    when the port type is not set. But from this warning it is not easy
    found out which device (driver) has no devlink port set.

    [ 3709.975552] Type was not set for devlink port.
