Eric Naim fb7d608aa7 ASoC: cs35l41: Always return 0 when a subsystem ID is found 
commit b0ff70e9d4 upstream.

When trying to get the system name in the _HID path, after successfully
retrieving the subsystem ID the return value isn't set to 0 but instead
still kept at -ENODATA, leading to a false negative:

[   12.382507] cs35l41 spi-VLV1776:00: Subsystem ID: VLV1776
[   12.382521] cs35l41 spi-VLV1776:00: probe with driver cs35l41 failed with error -61

Always return 0 when a subsystem ID is found to mitigate these false
negatives.

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.
