From 07df8afa0dd54b8b89ad8aa93994c0d55a4a5921 Mon Sep 17 00:00:00 2001 From: "Prakash, Sathya" Date: Fri, 8 Feb 2008 16:35:40 +0530 Subject: [PATCH] [SCSI] mpt fusion: Avoid racing when mptsas and mptcl module are loaded in parallel This patch sets the IOC pointer in drvrdata of pcidev before adding the IOC into the list of IOCs. Without this patch the driver oops when the mptsas and mptctl modules are loaded in parallel.
