Subject: [PATCH] ibmvnic: Do not close unopened driver during reset
References: bsc#1137752
Patch-mainline: v5.2-rc6
Git-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.
