Subject: SCSI: fix bugs and canonicalize NCR5380_intr drivers
From: Jeff Garzik <jeff@xxxxxxxxxx>
* Bug fix: Make sure request_irq() and free_irq() are called
with the same dev_id pointer argument.
* Bug fix: always pass 'irq' and 'dev_id' (aka 'dummy')
arguments to NCE5380_intr() when calling it manully. For some drivers
this doesn't matter, depending on whose copy of NCR5380_intr() is
being used.
* Bug fix: always pass Scsi_Host* to NCR5380_intr(). Most
get this right, but some pass NULL or some other random/ignored
value. For some drivers this doesn't matter, depending on whose copy
of NCR5380_intr() is being used.
* Wrap long request_irq() lines
