Danilo Krummrich 7ece3fc9b7 drm/nouveau: fence: fix type cast warning in nouveau_fence_emit()
Fix the following warning.

  drivers/gpu/drm/nouveau/nouveau_fence.c:210:45: sparse: sparse:
  incorrect type in initializer (different address spaces)
  @@     expected struct nouveau_channel *chan
  @@     got struct nouveau_channel [noderef] __rcu *channel

We're just about to emit the fence, there is nothing to protect against
yet, hence it is safe to just cast __rcu away.

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.
