Neither work item is drained before its resources are released on removal or probe failure. Disable read_work before freeing the IRQ, since the worker can re-enable it. Use request_irq()/free_irq() for explicit teardown. Unregister the regulator notifier before cancelling update_supply_work and disabling the regulator. Apply the same ordering to probe failures.
