None of the 53c700 drivers uses the SCSI pointer. Hence remove the code
from 53c700.c that clears two SCSI pointer fields. The 53c700 drivers are:

$ git grep -l 'include.*53c700'
drivers/scsi/53c700.c
drivers/scsi/a4000t.c
drivers/scsi/bvme6000_scsi.c
drivers/scsi/lasi700.c
drivers/scsi/mvme16x_scsi.c
drivers/scsi/sim710.c
drivers/scsi/sni_53c710.c
drivers/scsi/zorro7xx.c
