Subject: [PATCHv2 22/26] 53c700: move bus reset to host reset
Date: Fri, 25 Aug 2017 13:57:17 +0200	[thread overview]
Message-ID: <1503662241-127788-23-git-send-email-hare@suse.de> (raw)
In-Reply-To: <1503662241-127788-1-git-send-email-hare@suse.de>

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.
