[ofa-general] [RFC PATCH 07/14] RFC IB/ipath: Fix sparse warning about pointer signedness

[Roland Dreier]

ipath_count_units() wants its third parameter to be a u32 *, so change
the declaration of maxofallports in find_best_unit() to be a u32 instead
of a signed int.  This fixes

    drivers/infiniband/hw/ipath/ipath_file_ops.c:1654:47: warning: incorrect type in argument 3 (different signedness)
    drivers/infiniband/hw/ipath/ipath_file_ops.c:1654:47:    expected unsigned int [usertype] *maxportsp
    drivers/infiniband/hw/ipath/ipath_file_ops.c:1654:47:    got int *<noident>
