From fc70b11c716de901a0c1918079bd60ae3a17676e Mon Sep 17 00:00:00 2001

Subject: [PATCH 3514/4131] drm/amd/powerplay: Zero out power data in
AMDGPU_PP_SENSOR_GPU_POWER readout
Since 12 of the 16 bytes are not initialized with anything let's ensure they're
sensibly zeroed out otherwise debugfs callers will read back garbage
(because they assume debugfs wrote sensible data back...)
