If the card is unbound while these works are pending, callbacks fire after DAPM widgets are freed. rt5668 and rt5659 share the same pattern: the IRQ handler reschedules work after the codec is reset. Track IRQ acquisition so that disable_irq() only quiesces a line the driver owns, then drain all delayed works before resetting the hardware. twl6040 frees the plug-detect IRQ but does not drain the work that the handler schedules. wm8994 frees IRQs and firmware but does not cancel any of the four delayed works that IRQ handlers and DAPM events schedule.
