commit b0612fdba9afdce261bfb8684e0cece6f2e2b0bb upstream.
The simple-audio-card's microphone widget currently connects to the
headphone jack. Routing the microphone input to the microphone jack
allows for independent operation of the microphone and headphones.
This resolves the following boot-time kernel log message, which
indicated a conflict when the microphone and headphone functions were
not separated:
debugfs: File 'Headphone Jack' in directory 'dapm' already present!

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.
