Onur Özkan fc387a0704 checkpatch: detect unhandled placeholders in cover letters
Add a new check PLACEHOLDER_USE to detect unhandled placeholders.  This
prevents sending patch series with incomplete patches (mostly in cover
letters) containing auto generated subject or blurb lines.

These placeholders can be seen on mailing lists.  With this change,
checkpatch will emit an error when such text is found.

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.
