usb: cdns3: remove redundant if branch
cdns->role_sw->dev->driver_data gets set in routines showing below,
cdns_init
sw_desc.driver_data = cdns;
cdns->role_sw = usb_role_switch_register(dev, &sw_desc);
dev_set_drvdata(&sw->dev, desc->driver_data);
In cdns_resume,
cdns->role = cdns_role_get(cdns->role_sw); //line redundant
struct cdns *cdns = usb_role_switch_get_drvdata(sw);
dev_get_drvdata(&sw->dev)
return dev->driver_data
return cdns->role;
"line redundant" equals to,
cdns->role = cdns->role;
So fix this if branch.
