Martin Blumenstingl 8a7b179781 gpio: stp-xway: simplify error handling in xway_stp_probe()
Return early if devm_gpiochip_add_data() returns an error instead of
having two consecutive "if (!ret) ..." statements.

Also make xway_stp_hw_init() return void because it unconditionally
returns 0. While here also update the kerneldoc comment for
xway_stp_hw_init().

These changes makes the error handling within the driver consistent.
No functional changes intended.

README

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.
