Subject: [PATCH 7/7] scsi_error: streamline scsi_eh_bus_device_reset()
Date: Mon,  2 Oct 2023 17:59:15 +0200	[thread overview]
Message-ID: <20231002155915.109359-8-hare@suse.de> (raw)
In-Reply-To: <20231002155915.109359-1-hare@suse.de>

Streamline to use a similar code flow as the other reset functions.
