Kuninori Morimoto 0f312dc1eb ASoC: simple-card: fixup asoc_simple_probe() error handling 
commit 41bae58df4 upstream.

asoc_simple_probe() is used for both "DT probe" (A) and "platform probe"
(B). It uses "goto err" when error case, but it is not needed for
"platform probe" case (B). Thus it is using "return" directly there.

	static int asoc_simple_probe(...)
	{
 ^		if (...) {
 |			...
(A)			if (ret < 0)
 |				goto err;
 v		} else {
 ^			...
 |			if (ret < 0)
(B)				return -Exxx;
 v		}

		...
 ^		if (ret < 0)
(C)			goto err;
 v		...

	err:
(D)		simple_util_clean_reference(card);

		return ret;
	}

Both case are using (C) part, and it calls (D) when err case.
But (D) will do nothing for (B) case.
Because of these behavior, current code itself is not wrong,
but is confusable, and more, static analyzing tool will warning on
(B) part (should use goto err).

To avoid static analyzing tool warning, this patch uses "goto err"
on (B) part.

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.
