From: Alex Deucher <alexander.deucher@xxxxxxx> [ Upstream commit 598c30dbcc9434706f29a085a8eba4730573bcc2 ] Polaris and vegam use count for the value rather than level. This looks like a copy paste typo from when the code was adapted from previous asics. I'm not sure that the SMU actually uses this value, so I don't know that it actually is a bug per se.
