Subject: [PATCH AUTOSEL 4.19 26/60] ibmvnic: Do not close unopened driver during reset
Date: Wed, 26 Jun 2019 20:35:41 -0400 [thread overview]
Message-ID: <20190627003616.20767-26-sashal@kernel.org> (raw)
In-Reply-To: <20190627003616.20767-1-sashal@kernel.org>
From: Thomas Falcon <tlfalcon@linux.ibm.com>
[ Upstream commit 1f94608b0ce141be5286dde31270590bdf35b86a ]
Check driver state before halting it during a reset. If the driver is
not running, do nothing. Otherwise, a request to deactivate a down link
can cause an error and the reset will fail.
