[SCSI] sym53c8xx: Remove pci_dev pointer from sym_shcb
This structure is accessed by the device; the fewer Linux things in it, the better. Using the pci_dev pointer from the hostdata requires a lot of changes: - Pass Scsi_Host to a lot of routines which currently take a sym_hcb. - Set the Scsi_Host as the pci drvdata (instead of the sym_hcb) Signed-off-by: Matthew Wilcox <willy@linux.intel.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
