[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.
