Convert the arizona extcon driver into a helper library for direct use from the arizona codec-drivers, rather then being bound to a separate MFD cell. Note the probe (and remove) sequence is split into 2 parts: 1. The arizona_jack_codec_dev_probe() function inits a bunch of jack-detect specific variables in struct arizona_priv and tries to get a number of resources where getting them may fail with -EPROBE_DEFER. 2. Then once the machine driver has create a snd_sock_jack through snd_soc_card_jack_new() it calls snd_soc_component_set_jack() on the codec component, which will call the new arizona_jack_set_jack(), which sets up jack-detection and requests the IRQs. This split is necessary, because the IRQ handlers need access to the arizona->dapm pointer and the snd_sock_jack which are not available when the codec-driver's probe function runs. Note this requires that machine-drivers for codecs which are converted to use the new helper functions from arizona-jack.c are modified to create a snd_soc_jack through snd_soc_card_jack_new() and register this jack with the codec through snd_soc_component_set_jack().

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.
