Subject: [PATCH 1/1] cciss: remove overlapping PCI IDs

Patch 1 of 1

cciss: remove overlapping PCI IDs

From: Mike Miller <mike.miller@...com>

This patch removes the controller overlap between cciss and hpsa. It was
decided that no overlap should exist. All new controllers will use the hpsa
SCSI based driver.
