From 820682b1b34ebb97434c4abc00c744870364e2be Mon Sep 17 00:00:00 2001 From: Finn Thain Date: Mon, 10 Oct 2016 00:46:53 -0400 Subject: [PATCH] scsi: ncr5380: Store IO ports and addresses in host private data The various 5380 drivers inconsistently store register pointers either in the Scsi_Host struct "legacy crap" area or in special, board-specific members of the NCR5380_hostdata struct. Uniform use of the latter struct makes for simpler and faster code (see the following patches) and helps to reduce use of the NCR5380_implementation_fields macro.
