Serge Semin says: ==================== net: pcs: xpcs: Cleanups before adding MMIO dev support As stated in the subject this series is a short prequel before submitting the main patches adding the memory-mapped DW XPCS support to the DW XPCS and DW *MAC (STMMAC) drivers. Originally it was a part of the bigger patchset (see the changelog v2 link below) but was detached to a preparation set to shrink down the main series thus simplifying it' review. The patchset' content is straightforward: drop the redundant sentinel entry and the header files; return EINVAL errno from the soft-reset method and make sure that the interface validation method return EINVAL straight away if the requested interface isn't supported by the XPCS device instance. All of these changes are required to simplify the changes being introduced a bit later in the framework of the memory-mapped DW XPCS support patches.

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.
