Geert Uytterhoeven 33eced402b can: rcar_canfd: Improve error messages
Improve printed error messages:
  - Replace numerical error codes by mnemotechnic error codes, to
    improve the user experience in case of errors,
  - Drop parentheses around printed numbers, cfr.
    Documentation/process/coding-style.rst,
  - Drop printing of an error message in case of out-of-memory, as the
    core memory allocation code already takes care of this.

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.
