Check for pow0 port first before calling the interface helper. This avoids the following error log when setting up pow0 interface: cvmx_helper_get_interface_num: Illegal IPD port number Signed-off-by: Aaro Koskinen <aaro.koskinen@nokia.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
