Kuninori Morimoto 139fa599ce ASoC: rsnd: check rsnd_adg_clk_enable() return value
rsnd_adg_clk_enable() might be failed for some reasons, but it doesn't
check return value for now. In such case, we might get below WARNING from
clk_disable() during probe or suspend. Check rsnd_adg_clk_enable() return
value.

    clk_multiplier already disabled
    ...
    Call trace:
     clk_core_disable+0xd0/0xd8 (P)
     clk_disable+0x2c/0x44
     rsnd_adg_clk_control+0x80/0xf4

According to Geert, it happened only 7 times during the last 2 years.
So I have reproduced the issue and created patch by Intentionally making
an error.

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 reStructuredText 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.
