Wait, I did not post a 'Reviewed-by' tag for this patch!
I think the patch should be ok, but I'm still not super happy about the resource management involving devfreq in general (see discussion on https://patchwork.freedesktop.org/patch/394291/?series=82476&rev=1). It's not really something introduced by this patch, but if it ever gets fixed releasing the cooling device at the end of msm_gpu_cleanup() after everything else might cause trouble.
In summary, I'm supportive of landing this patch, but reluctant to 'sign it off' because of the above.
In any case:
