From d9dcb4ba791de2a06b19ac47cd61601cf3d4e208 Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Thu, 30 Jun 2011 17:38:32 -0700 Subject: isci: unify isci_host and scic_sds_controller Remove the distinction between these two implementations and unify on isci_host (local instances named ihost). Hmmm, we had two 'oem_parameters' instances, one was unused... nice.
