[ Upstream commit 6e54919cb541fdf1063b16f3254c28d01bc9e5ff ]
The microphone detection work scheduled by a prior jack insertion interrupt may still be in a pending state or under execution when a jack ejection interrupt has been fired.
This might lead to a racing condition or nau8821_jdet_work() completing after nau8821_eject_jack(), which will override the currently disconnected state of the jack and incorrectly report the headphone or the headset as being connected.
Cancel any pending jdet_work or wait for its execution to finish before attempting to handle the ejection interrupt.
Proceed similarly before launching the eject handler as a consequence of detecting an invalid insert interrupt.
