Guenter Roeck 3825263486 drm/nouveau/nvkm: Replace -ENOSYS with -ENODEV 
commit e8f71f89236ef82d449991bfbc237e3cb6ea584f upstream.

nvkm test builds fail with the following error.

  drivers/gpu/drm/nouveau/nvkm/engine/device/ctrl.c: In function 'nvkm_control_mthd_pstate_info':
  drivers/gpu/drm/nouveau/nvkm/engine/device/ctrl.c:60:35: error: overflow in conversion from 'int' to '__s8' {aka 'signed char'} changes value from '-251' to '5'

The code builds on most architectures, but fails on parisc where ENOSYS
is defined as 251.

Replace the error code with -ENODEV (-19).  The actual error code does
not really matter and is not passed to userspace - it just has to be
negative.

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 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.
