drivers/scsi/csiostor/csio_hw_t5.c: In function csio_t5_mc_read:
drivers/scsi/csiostor/csio_hw_t5.c:151:11: warning: variable 
mc_bist_status_rdata_reg set but not used [-Wunused-but-set-variable]
drivers/scsi/csiostor/csio_hw_t5.c: In function csio_t5_edc_read:
drivers/scsi/csiostor/csio_hw_t5.c:199:38: warning: variable
