Subject: RE: [PATCH] drm/amd/powerplay: check for invalid profile mode before 
switching

It's kind of an improvement of the previous commit
    drm/amd/powerplay: update current profile mode only when it's really applied

    No need to update current profile mode if the new profile mode
    does not take effect in fact.

Maybe @Deucher, Alexander can help to combine them as one.

Regards,
Evan
