Russell King says: ==================== net: pcs: xpcs: yet more cleanups I've found yet more potential for cleanups in the XPCS driver. The first patch switches to using generic register definitions. Next, there's an overly complex bit of code in xpcs_link_up_1000basex() which can be simplified down to a simple if() statement. Then, rearrange xpcs_link_up_1000basex() to separate out the warnings from the functional bit. Next, realising that the functional bit is just the helper function we already have and are using in the SGMII version of this function, switch over to that. We can now see that xpcs_link_up_1000basex() and xpcs_link_up_sgmii() are basically functionally identical except for the warnings, so merge the two functions. Next, xpcs_config_usxgmii() seems misnamed, so rename it to follow the established pattern. Lastly, "return foo();" where foo is a void function and the function being returned from is also void is a weird programming pattern. Replace this with something more conventional. With these changes, we see yet another reduction in the amount of code in this driver.

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.
