* isci: fix fragile/conditional isci_host lookupsDan Williams2011-07-031-1/+1
| | | | | | | | | | | | | | A domain_device can always reference back to ->lldd_ha unlike local lldd structures. Fix up cases where the driver uses local objects to look up the isci_host. This also changes the calling conventions of some routines to expect a valid isci_host parameter rather than re-lookup the pointer on entry. Incidentally cleans up some macros that are longer to type than the open-coded equivalent: isci_host_from_sas_ha isci_dev_from_domain_dev Signed-off-by: Dan Williams <dan.j.williams@intel.com>
