Well, the aic7xxx subdirectory is a nightmare of CodingStyle non
conformities ... you can see the return (ENOMEM) just in this patch.
That's two problems: the brackets and non negative error returns which
are later converted to negative ones thus inviting sign problems.  The
driver is also about 3x bigger than it should be because of the vestiges
of the BSD glue layer.  However, I think my life is too short to apply
the 32,554 patches it would take to correct this an issue at a time.

This is one of those drivers we tolerate because we must and we fix up
around the regions we have to touch.
