[ Upstream commit040e3360af] Put the SGTL5000 in a silent/safe state on shutdown/remove, this is required since the SGTL5000 produces a constant noise on its output after it is configured and its clock is removed. Without this change this is happening every time the module is unbound/removed or from reboot till the clock is enabled again. The issue was experienced on both a Toradex Colibri/Apalis iMX6, but can be easily reproduced everywhere just playing something on the codec and after that removing/unbinding the driver.

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.
