From 8a4df120b0712a12134d0d9435ccaec1c12b07a7 Mon Sep 17 00:00:00 2001 From: Tomohiro Kusumi Date: Fri, 11 Jan 2008 01:53:00 -0500 Subject: [PATCH] [SCSI] lpfc 8.2.4 : Make lpfc legacy I/O port free This is a patch written by Tomohiro Kusumi and submitted to linux-scsi: http://marc.info/?l=linux-scsi&m=118673720712152&w=2 The original patch comment: This patch makes Emulex lpfc driver legacy I/O port free. It has already been acked quite long time ago. So I resubmit the patch. http://lkml.org/lkml/2006/11/22/28 Current lpfc driver is already using pci_select_bars() and pci_enable_device_bars() when the PCI bus has been reset. So I think this patch should also be acked.
