free_irq() waits until all handlers for this IRQ have completed. As the relevant handler (mv88e6xxx_g1_irq_thread_fn()) takes the chip's reg_lock it might never return if the thread calling free_irq() holds this lock. For the same reason kthread_cancel_delayed_work_sync() in the polling case must not hold this lock. Also first free the irq (or stop the worker respectively) such that mv88e6xxx_g1_irq_thread_work() isn't called any more before the irq mappings are dropped in mv88e6xxx_g1_irq_free_common() to prevent the worker thread to call handle_nested_irq(0) which results in a NULL-pointer exception.
