Hmm, vger does not like the driver name of the Adaptec driver. ;-)

Subject: [PATCH] aic7xxx claims all checked EISA io ranges
User-Agent: Mutt/1.4i
From: Robert Schiele <[e-mail]>

Hello.

Some days ago a bug was introduced in aic7xxx by applying the aic7xxx driver
upgrade to both the 2.4 and the 2.5 tree.  This bug makes aic7xxx to claim =
all
the ioport ranges that he checks while scanning for EISA cards.  Takashi Iw=
ai
and me iterated over the sources to finally find that the result value check
of the request_region() is negated.

Because of that the following patch goes to Justin to fix it in driver
development tree, to the official tree maintainers to fix it there, and to
Alan, because you sent this driver update to Marcelo, so I assume the same
problem is in your tree.

The patch applies to both, the 2.4 and the 2.5 tree.

And now for the trivial but obvious patch:
