mqprio: Avoid panic if no options are provided [ Upstream commit 7838f2ce36b6ab5c13ef20b1857e3bbd567f1759 ] Userspace may not provide TCA_OPTIONS, in fact tc currently does so not do so if no arguments are specified on the command line. Return EINVAL instead of panicing. Signed-off-by: Thomas Graf <tgraf@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
