Subject: scsi: 53c700: move bus reset to host reset
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=44257a1b36fc7b69c021d25ab0d18bb734846ccb;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

scsi: 53c700: move bus reset to host reset

bus reset always returns SUCCESS, meaning host reset was never
tested. At the same time the only difference to the HBA is a missing
call to NCR_700_chip_reset().  So add the missing call to bus reset,
drop host reset, and move bus reset to host reset.
