[PATCH] fix ips driver compile problems

   This patch has been floating inside IBM for a bit, but it appears
that no one passed it back up to you, yet.  I don't know who wrote it,
but it applies to 2.5.8 and the ServeRAID driver works just fine with it
applied.  Without it, the driver fails to compile.
