Lyude Paul 0059a9081a drm/nouveau/kms/nv50-: Fix CRC-related compile errors with debugfs disabled
Looks like I made the mistake of forgetting to check whether or not this
would build without CONFIG_DEBUG_FS, as the Kbuild bot reported some
issues building with tegra_defconfig:

So, fix the inline function declarations we use in
drm/drivers/gpu/drm/nouveau/dispnv50/crc.h when CONFIG_DEBUG_FS is
enabled.

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.
