Tvrtko Ursulin 91875c22a3 drm/i915: Don't use DRM_DEBUG_WARN_ON for ring unexpectedly not idle
DRM_DEBUG_WARN_ON should only be used when we are certain CI is guaranteed
to exercise a certain code path, so in case of values coming from MMIO
reads we cannot be sure CI will have all the possible SKUs and parts, or
that it will catch all possible error conditions. Use drm_warn instead.

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.
