From 67b2009ae26ece6a54d0b689827903f53d6d21e6 Mon Sep 17 00:00:00 2001 From: James Bottomley Date: Thu, 3 May 2007 11:13:08 -0500 Subject: [SCSI] ibmmca: convert to new probing API and fix oopses This is basically a straight conversion. I have one of these things, so I know it works ... my problem is that it has a wierd SCA like connector, so I can't connect anything to it (no cables). However, previously it panic'd in the interrupt, now it completes a bus scan.
