[PATCH] extcon: adc-jack: cancel delayed work on remove

[Hongyan Xu]

The IRQ handler queues handler as delayed work. The remove callback
passes its embedded work_struct to cancel_work_sync(), which cannot
cancel a pending delayed-work timer.

Free the IRQ to stop new queueing, then cancel the delayed work itself
before devres releases the containing object.
