[PATCH v2 3/4] ASoC: twl6040: cancel headset jack work on component removal

[Tristan Madani <tristmd@gmail.com>]

The twl6040 codec driver initializes a delayed work for headset jack
detection (hs_jack.work) but the component remove callback only frees
the plug IRQ without cancelling the pending work. If the IRQ fires and
schedules the work shortly before removal, it can execute on freed
memory.

Add cancel_delayed_work_sync() in twl6040_remove() before freeing the
IRQ to ensure no stale work remains queued.
