sound/soc/soc-core.c: soc_remove_component() unconditionally calls snd_soc_component_set_jack(component, NULL, NULL); on any components being removed. This means that on machines where the machine-driver does not provide a jack through snd_soc_component_set_jack() es8316_disable_jack_detect() will still get called and at this time es8316->jack will be NULL and the es8316->jack->status check in es8316_disable_jack_detect() will lead to a NULL pointer deref. Fix this by checking for es8316->jack bein NULL at the start of es8316_disable_jack_detect() and turn the function into a no-op in that case.

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.
