Subject: [PATCH 3544/4256] drm/amd/powerplay: fix message of SetHardMinByFreq
failed when feature is disabled
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
the direct send message to smc to set hard clokc will failed
when smc clock dpm feature is disabled.
so use function of smu_set_hard_freq_range to replace it.
the function will check feature enablement.
eg: when uclk (mclk) dpm feature is disabled on navi10
[ 300.675901] amdgpu: [powerplay] failed send message: SetHardMinByFreq(28)
param: 0x00020064 response 0xfffffffb
