Kevin Wang 0092130675 drm/amd/powerplay: add sensor lock support for smu ... when multithreading access sysfs of amdgpu_pm_info at the sametime. the swsmu driver cause smu firmware hang. eg: single thread access: Message A + Param A ==> right Message B + Param B ==> right Message C + Param C ==> right multithreading access: Message A + Param B ==> error Message B + Param A ==> error Message C + Param C ==> right the patch will add sensor lock(mutex) to avoid this error.
