           Summary: mthca/mthca_cmd.c:1362: suspicious call to MTHCA_PUT
           Product: Drivers
           Version: 2.5
    Kernel Version: 3.6-rc2
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Infiniband/RDMA
        AssignedTo: drivers_infiniband-rdma-ztI5WcYan/[email protected]
        ReportedBy: [email protected]
        Regression: No

I just ran the static analyser cppcheck over the source code of the linux kernel version 3.6-rc2.

It said

[linux-3.6-rc2/drivers/infiniband/hw/mthca/mthca_cmd.c:1362]: (warning) Using sizeof with a numeric constant as function argument might not be what you intended.

The source code is

        MTHCA_PUT(inbox, 0x1, INIT_HCA_FLAGS1_OFFSET);

The 2nd parameter to the macro looks suspicious. All the other calls to MTHCA_PUT do not have a value.

Suggest code rework.
