Daniel Golle fec6e69f0a net: phy: mxl-gpy: fix bogus error on USXGMII and integrated PHY
[ Upstream commit ec3803b591 ]

As the interface mode doesn't need to be updated on PHYs connected with
USXGMII and integrated PHYs, gpy_update_interface() should just return 0
in these cases rather than -EINVAL which has wrongly been introduced by
commit 7a495dde27 ("net: phy: mxl-gpy: Change gpy_update_interface()
function return type"), as this breaks support for those PHYs.

Fixes: 7a495dde27 ("net: phy: mxl-gpy: Change gpy_update_interface() function return type")

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.
