Then in case of issues we may prevent the driver from showing us if and how it can handle them. Don't arm the timer before sysfs operations which are essential for a subtest. v2: Refresh, - don't time out on hot driver rebind / hot device restore in *-lateclose variants, those operations haven't been covered by other subtests.
