Subject: [PATCH AUTOSEL 5.17 41/49] scsi: mpt3sas: Fail reset operation if config request timed out
Date: Mon, 11 Apr 2022 20:43:59 -0400	[thread overview]
Message-ID: <20220412004411.349427-41-sashal@kernel.org> (raw)
In-Reply-To: <20220412004411.349427-1-sashal@kernel.org>

From: Sreekanth Reddy <sreekanth.reddy@broadcom.com>

[ Upstream commit f61eb1216c959f93ffabd3b8781fa5b2b22f8907 ]

As part of controller reset operation the driver issues a config request
command. If this command gets times out, then fail the controller reset
operation instead of retrying it.
