From: Nicholas Kazlauskas <[email protected]>
commit e2bf3723db563457c0abe4eaeedac25bbbbd1d76 upstream.
[Why]
DC uses these to raise the voltage as needed for higher dispclk/dppclk
and to ensure that we have enough bandwidth to drive the displays.
There's a bug preventing these from actuially sending messages since
it's checking the actual clock (which is 0) instead of the incoming
clock (which shouldn't be 0) when deciding to send the hardmin.
[How]
Check the clocks != 0 instead of the actual clocks.
Fixes: 9ed9203c3ee7 ("drm/amd/powerplay: rv dal-pplib interface refactor
powerplay part")
