Subject: [PATCH 7/7] scsi_error: streamline scsi_eh_bus_device_reset()
Date: Mon,  2 May 2022 23:59:49 +0200	[thread overview]
Message-ID: <20220502215953.5463-15-hare@suse.de> (raw)
In-Reply-To: <20220502215953.5463-1-hare@suse.de>

From: Hannes Reinecke <hare@suse.com>

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