Adding this patch to 2.6.32 (and likely 2.6.31 as well) breaks building the
current stable queue:

As it seems, the scsih struct member of MPT2SAS_ADAPTER was only added to 
drivers/scsi/mpt2sas/mpt2sas_base.h during the 2.6.33 merge window, so 
this patch doesn't seem to be necessary for <2.6.33-rcX.
