Whoops, that's one too many empty line...
Roland, when you apply this patch, could you apply the following patch on top:

--- a/drivers/infiniband/hw/ehca/hcp_if.c
+++ b/drivers/infiniband/hw/ehca/hcp_if.c
@@ -157,7 +157,6 @@ static long ehca_plpar_hcall9(unsigned l
        int i, sleep_msecs, lock_is_set = 0;
        unsigned long flags;

-
        ehca_gen_dbg("opcode=%lx arg1=%lx arg2=%lx arg3=%lx arg4=%lx "
                     "arg5=%lx arg6=%lx arg7=%lx arg8=%lx arg9=%lx",
                     opcode, arg1, arg2, arg3, arg4, arg5, arg6, arg7,


Thanks!
