[ Upstream commit 3b3312f28ee2d9c386602f8521e419cfc69f4823 ]
Return an error from driver probe if the DEVID read from the chip is not
one supported by this driver.
In cs35l56_hw_init() there is a check for valid DEVID, but the invalid
case was returning the value of ret. At this point in the code ret == 0
so the caller would think that cs35l56_hw_init() was successful.

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.
