Subject: [PATCH] remove iph5526 driver

From: Christoph Hellwig <[email-masked]>
Date: Mon, 6 Sep 2004 12:10:14 +0200

This driver is for totally obsolete early fibrechannel hardware and
doesn't compile anymore since early 2.5.x.  In addition it'll require
a major rewrite to fit into the current framework for fc drivers.
