+Subject: [PATCH 3238/4256] drm/amd/powerplay: Allow changing of fan_control in
+ smu_v11_0
+
+[Why]
+Before this change, the fan control state on smu_v11 was not able to be
+changed because the capability check for checking if the fan control
+capability existed was inverted.
+
+[How]
+The capability check for fan control in smu_v11_0_auto_fan_control was
+inverted, to correctly check for the absence, instead of presence of fan
+control capabilities.
