[PATCH 2.5.42] aacraid code changes

From: Mark Haverkamp (markh@osdl.org)
Date: Mon Oct 14 2002 - 13:25:06 EST


Here are a couple changes to the aacraid code that I made to get the
module to load and run. The change in aachba.c is a work around so I
could get the module to load. The sc_request element is always NULL as
far as I can tell. I haven't yet found an alternate place to get the
rq_dev information. With this change and the one to commctrl.c, I have
been able to get access to the drives and use them.

Mark.
