Subject: drm/amd/pm: Set no fan control flag as needed.
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=73ab8efc7fdf683f7415c010990d9a1a16fae464;p=linux.git

drm/amd/pm: Set no fan control flag as needed.

For GPUs that don't support fan control, set the no fan control flag so
that they don't appear in hwmon sensors.
