Since commit |dd3bd23eb4("can: rcar_canfd: Add Renesas R-Car CAN FD driver") the rcar_canfd driver can be compile tested on all architectures. On non OF enabled archs, or archs where OF is optional (and disabled in the .config) the compilation throws the following warning: | drivers/net/can/rcar/rcar_canfd.c:2020:34: warning: unused variable 'rcar_canfd_of_table' [-Wunused-const-variable] | static const struct of_device_id rcar_canfd_of_table[] = { | ^ This patch fixes the warning by marking the variable rcar_canfd_of_table as __maybe_unused.

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.
