We used to call directly hda_jackpoll_work() from a couple of places for updating the jack and notify to user-space, but this makes rather the code flow fragile. Namely, because of those direct calls, hda_jackpoll_work() uses snd_hda_power_up_pm() and *_down_pm() calls instead of the standard snd_hda_power_up() and *_down() calls. The latter pair assures the runtime PM resume sync, so it can avoid the race against the PM callbacks gracefully, while the former pair may continue if called concurrently, hence it may race (by design). In this patch, we change the call pattern of hda_jackpoll_work(); now all callers are replaced with the standard snd_hda_jack_report_sync() and the additional schedule_delayed_work(). Since hda_jackpoll_work() is called only from the associated work, it's always outside the PM code path, and we can safely use snd_hda_power_up() and *_down() there instead. This allows us to remove the racy check of power-state in hda_jackpoll_work(), as well as the tricky cancel_delayed_work() and rescheduling at hda_codec_runtime_suspend().

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 reStructuredText 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.
