Subject[2.6 patch] SCSI: cleanups
This patch contains the following cleanups:
- make needlessly global code static
- remove the following unused functions:
- scsi.h: print_driverbyte
- scsi.h: print_hostbyte
- #if 0 the following unused functions:
- constants.c: scsi_print_hostbyte
- constants.c: scsi_print_driverbyte
- remove the following unneeded EXPORT_SYMBOL's:
- hosts.c: scsi_host_lookup
- scsi.c: scsi_device_cancel
- scsi_lib.c: scsi_device_resume
