From 0d0c79747e362ff54adc6418d2990d49cad9395d Mon Sep 17 00:00:00 2001 From: "Moore, Eric Dean" Date: Fri, 22 Apr 2005 18:02:09 -0400 Subject: [PATCH] [SCSI] mptfusion: mptscsih Split driver support (1) mptscsih.c: Remove credits, -sralston references , update copyright (2) mptscsih.c: split driver support (3) mptscsih.c: module_init, module_exit, and probe routines moved to new stub drivers, mptfc and mptspi (4) mptscsih.c: some global parameters are moved to MPT_SCSI_HOST (5) mptscsih.c: removed scsi_device_online check.
