Since the IRQ is registered with devm_request_threaded_irq(), it remains active until after the component remove callback returns. The IRQ handler (rt5659_irq) schedules jack_detect_work, so a late interrupt can queue work that runs against a reset codec. Track successful IRQ acquisition with a flag so that disable_irq() only quiesces a line this driver actually owns. Guard the cancel_delayed_work_sync() call with a flag that tracks whether the work was initialized, since INIT_DELAYED_WORK is only called for specific jd_src configurations (JD3, JD_HDA_HEADER) and cancelling an uninitialized work is undefined behavior. On component remove, disable the IRQ to synchronize with any running handler and prevent new enqueues, then drain the residual jack_detect_work synchronously before resetting the hardware. On the next component probe (card rebind), re-enable the IRQ to restore jack detection.
