From dc22f16d4e46cee699c3835cc6e2a8005023517f Mon Sep 17 00:00:00 2001 From: Eric Moore Date: Thu, 6 Jul 2006 11:23:14 -0600 Subject: [PATCH] [SCSI] mptsas: use unnumbered port API and remove driver porttracking This allows us to be rid of the machinery in mptsas for creating and tracking port numbers. Since mptsas is merely inventing the numbers, the SAS transport class may as well do it instead.
