Subject: drm/amdgpu/pp: switch smu callback type for get_argument()
Git-commit: 59f20f5a0c9767a8b66688b84e72a345b4dc1bc1
Patch-mainline: v4.19-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

return a uint32_t rather than an int to properly reflect
what the function does.
