From 852809559e4680ba4768262a6c3d21454fcd460e Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Tue, 28 Jun 2011 15:05:53 -0700 Subject: isci: unify isci_phy and scic_sds_phy They are one in the same object so remove the distinction. The near duplicate fields (owning_port, and isci_port) will be cleaned up after the scic_sds_port isci_port unification.
