[ 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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
