Subject: [PATCH 3/3] mpt fusion: Fix for module load error when mptctl and mptsas are loaded in parallel
Date: Fri, 11 Jan 2008 14:46:30 +0530 [thread overview]
Message-ID: <20080111091630.GD4161@lsil.com> (raw)
This patch fixes a panic at mptctl_probe -> mutex_init if the mptsas and mptcl module are loaded in parallel, this is because IOC is NULL, the fix is in mpt_device_register to call probe only with non-zero IOC pointer.
