Thomas Böhler b5f9e4b810 drm/panic: allow verbose boolean for clarity 
commit 27aef8a52e upstream.

Clippy complains about a non-minimal boolean expression with
`nonminimal_bool`:

    error: this boolean expression can be simplified
       --> drivers/gpu/drm/drm_panic_qr.rs:722:9
        |
    722 |         (x < 8 && y < 8) || (x < 8 && y >= end) || (x >= end && y < 8)
        |         ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

        = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#nonminimal_bool
        = note: `-D clippy::nonminimal-bool` implied by `-D warnings`
        = help: to override `-D warnings` add `#[allow(clippy::nonminimal_bool)]`
    help: try
        |
    722 |         !(x >= 8 || y >= 8 && y < end) || (x >= end && y < 8)
        |         ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    722 |         (y >= end || y < 8) && x < 8 || (x >= end && y < 8)
        |         ~~~~~~~~~~~~~~~~~~~~~~~~~~~~

While this can be useful in a lot of cases, it isn't here because the
line expresses clearly what the intention is. Simplifying the expression
means losing clarity, so opt-out of this lint for the offending line.

README 

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.
