Alex Deucher e281d5940a drm/amdgpu/swsmu/i2c: return an error if the SMU is not running
Return an error if someone tries to use the i2c bus when the
SMU is not running.  Otherwise we can end up sending commands
to the SMU which will either get ignored or could cause other
issues depending on what state the GPU and SMU are in.

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.
