Ilpo Järvinen 756762aeb1 drm/radeon: Use RMW accessors for changing LNKCTL2
Convert open coded RMW accesses for LNKCTL2 to use
pcie_capability_clear_and_set_word() which makes its easier to
understand what the code tries to do.

LNKCTL2 is not really owned by any driver because it is a collection of
control bits that PCI core might need to touch. RMW accessors already
have support for proper locking for a selected set of registers
(LNKCTL2 is not yet among them but likely will be in the future) to
avoid losing concurrent updates.

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.
