From a6afb728573a945a844687362b4eaa9cb2eaaa74 Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Wed, 21 Mar 2012 21:09:10 -0700 Subject: [PATCH] libsas: drop sata port multiplier infrastructure On the way to add a new sata_device field, noticed that libsas is carrying port multiplier infrastructure that is explicitly disabled by sas_discover_sata(). The aic94xx touches the unused port_no, so leave that field in case there was some use for it.
