Shengjiu Wang 0dddb5642d ASoC: fsl_xcvr: Fix event generation in fsl_xcvr_arc_mode_put()
[ Upstream commit 1b61c8103c ]

ALSA controls should return 1 if the value in the control changed but the
control put operation fsl_xcvr_arc_mode_put() only returns 0 or a negative
error code, causing ALSA to not generate any change events.

Add a suitable check in the function before updating the arc_mode
variable.

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.
