drm/amdgpu: Fix check for DPM when returning max clock (944effd3) · Commits · 戴 / test

pp_funcs may not exist, while dpm may be enabled. This change ensures that KFD topology will report the same as pp_dpm_sclk, as the conditions for reporting them will be the same. Otherwise, we may see the issue where KFD reports "100MHz" in topology as the max speed, while DPM is working correctly. Signed-off-by:
