If phylib is built as a module and CONFIG_MDIO_DEVICE is 'y', the
mdio_device and mdio_bus code will be in the phylib module, not in the
kernel image. Meanwhile we build mdio_devres depending on the
CONFIG_MDIO_DEVICE symbol, so if it's 'y', it will go into the kernel
and we'll hit the following linker error:
ld: drivers/net/phy/mdio_devres.o: in function `devm_mdiobus_alloc_size':
>> drivers/net/phy/mdio_devres.c:38: undefined reference to `mdiobus_alloc_size'
ld: drivers/net/phy/mdio_devres.o: in function `devm_mdiobus_free':
>> drivers/net/phy/mdio_devres.c:16: undefined reference to `mdiobus_free'

>> drivers/net/phy/mdio_devres.c:87: undefined reference to `__mdiobus_register'
ld: drivers/net/phy/mdio_devres.o: in function `devm_mdiobus_unregister':
>> drivers/net/phy/mdio_devres.c:53: undefined reference to `mdiobus_unregister'
ld: drivers/net/phy/mdio_devres.o: in function `devm_of_mdiobus_register':
>> drivers/net/phy/mdio_devres.c:120: undefined reference to `of_mdiobus_register'
Add a hidden Kconfig option for MDIO_DEVRES which will be currently
selected by CONFIG_PHYLIB as there are no non-phylib users of these
helpers.

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.
