From 4b33981ade7cf723f3f32809e34192376c9a10f8 Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Fri, 6 May 2011 17:36:38 -0700 Subject: isci: unify phy data structures Make scic_sds_phy a member of isci_phy and merge their lifetimes which means removing the phy table from scic_sds_controller in favor of the one at that isci_host level.
