[PATCH] sym53c500_cs driver update

[Bob Tracy]

(Previously posted a month ago to linux-kernel and linux-scsi with
copies to James Bottomley and Christoph Hellwig.  No feedback received.
Would like to see this included in 2.6.10.  Thanks!)

The attached minor patch to linux/drivers/scsi/pcmcia/sym53c500_cs.c
allows interrupt sharing, which is evidently a "must have" feature for
at least G4 PowerBooks (ppc architecture).  The other user of the New
Media Bus Toaster reports that his powerbook consistently assigns the
yenta CardBus controller IRQ to whatever card he inserts.

Applies to version 0.9b of the sym53c500_cs driver, as included with
the 2.6.9 kernel.
