[SCSI] hptiop: add more adapter models and other fixes
Most code changes were made to support adapters based on Marvell IOP, plus some other fixes. - add more PCI device IDs - support for adapters based on Marvell IOP - fix a result code translation error on big-endian systems - fix resource releasing bug when scsi_host_alloc() fail in hptiop_probe() - update scsi_cmnd.resid when finishing a request - correct some coding style issues [akpm@linux-foundation.org: type fixes] Signed-off-by: HighPoint Linux Team <linux@highpoint-tech.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>

The driver registers char device "hptiop" to communicate with HighPoint RAID

management software. Its ioctl routine acts as a general binary interface

between the IOP firmware and HighPoint RAID management software. New management
