Subject: [PATCH] Future Domain SCSI controller fix for 2.4.x
Date: Mon, 14 May 2001 17:07:32 -0400	[thread overview]
Message-ID: <01051417073200.06553@hlclabs.dynip.com> (raw)


Hi, the driver for this card seems to have missed out on one of the changes 
to the SCSI layer between 2.2 and 2.4.  Specifically, scsi_set_pci_device 
now wants an entire SCSI host object, instead of just the pci_dev part.   
Without the patch, we get a null kernel pointer dereference when the driver 
is initialized.  With the single-line update, the driver works again.  I've 
also included a patch to change an udelay loop into the equivalent mdelay 
call for code readability purposes.  These are both against 2.4.4; please 
apply.
