[PATCH] Update PnP IDE (2/6)

From: Adam Belay (ambx1@neo.rr.com)
Date: Sat Jan 25 2003 - 15:15:16 EST


This patch converts the ide driver to the latest pnp changes. I do not have this
hardware so this patch was only tested for compilation.

Please note: I added ide_unregister to ide.h becuase I needed it for the driver
conversion. Please let me know if this is not the proper unregister api for ide
devices.
