Subject: PATCH: 2.5.27 - Fix up the atp870u scsi driver
Date: 22 Jul 2002 18:58:40 +0100 [thread overview]
Message-ID: <1027360720.31782.61.camel@irongate.swansea.linux.org.uk> (raw)
This imports the 2.4 fixes missing from 2.5, then rewrites chunks of it
so that its sane enough to add the pci dma api functionality.
This driver wants a much bigger workover before 2.6 really
