From 099175c94a221fa2723b7273883c98cd32efe900 Mon Sep 17 00:00:00 2001 From: James Bottomley Date: Thu, 21 Apr 2005 22:50:33 -0400 Subject: [SCSI] remove PCI2000 and PCI2220i drivers From: Christoph Hellwig Both drivers are marked broken and haven't compiled since very early 2.5.x. And they're for IDE hardware so they shouldn't have been written to the SCSI layer at all.
