Subject: [PATCH AUTOSEL 4.19 168/191] scsi: NCR5380: Clear all unissued commands on host reset
Date: Sat,  9 Nov 2019 21:39:50 -0500
Message-ID: <20191110024013.29782-168-sashal@kernel.org> (raw)
In-Reply-To: <20191110024013.29782-1-sashal@kernel.org>

From: Hannes Reinecke <hare@suse.com>

[ Upstream commit 1aeeeed7f03c576f096eede7b0384f99a98f588c ]

When doing a host reset we should be clearing all outstanding commands, not
just the command triggering the reset.
