Subject: re: mlx4_core: Modify driver initialization flow to accommodate
 SRIOV for Ethernet

Hello Jack Morgenstein,

The patch ab9c17a009ee: "mlx4_core: Modify driver initialization flow 
to accommodate SRIOV for Ethernet" from Dec 13, 2011, leads to the 
following static checker warning:

drivers/net/ethernet/mellanox/mlx4/main.c:424 mlx4_slave_cap()
	warn: suspicious bitop condition

   423          /*fail if the hca has an unknown capability */
   424          if ((hca_param.global_caps | HCA_GLOBAL_CAP_MASK) !=
   425              HCA_GLOBAL_CAP_MASK) {
   426                  mlx4_err(dev, "Unknown hca global capabilities\n");
   427                  return -ENOSYS;
   428          }

The test sort of makes sense but HCA_GLOBAL_CAP_MASK is zero so we could
as well say:

	if (hca_param.global_caps) { ...
