Geert Uytterhoeven fd8f64df95 mdio_bus: Fix init if CONFIG_RESET_CONTROLLER=n
Commit 1d4639567d ("mdio_bus: Fix PTR_ERR applied after initialization
to constant") accidentally changed a check from -ENOTSUPP to -ENOSYS,
causing failures if reset controller support is not enabled.  E.g. on
r7s72100/rskrza1:

    sh-eth e8203000.ethernet: MDIO init failed: -524
    sh-eth: probe of e8203000.ethernet failed with error -524

Seen on r8a7740/armadillo, r7s72100/rskrza1, and r7s9210/rza2mevb.

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.
