From: Thomas Falcon <redacted> [ 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. Signed-off-by: Thomas Falcon <redacted> Signed-off-by: David S.
