Hi, In my end, this declaration of function 'do_div' can be founded. In file included from ./arch/x86/include/asm/div64.h:63:0, from include/linux/math64.h:5, from ./arch/x86/include/asm/processor.h:30, from ./arch/x86/include/asm/atomic.h:6, from include/linux/atomic.h:4, from include/linux/mutex.h:18, from include/linux/seq_file.h:7, from drivers/gpu/drm/amd/powerplay/inc/hwmgr.h:26, from drivers/gpu/drm/amd/amdgpu/../powerplay/hwmgr/tonga_thermal.h:27, from drivers/gpu/drm/amd/amdgpu/../powerplay/hwmgr/tonga_thermal.c:24: drivers/gpu/drm/amd/amdgpu/../powerplay/hwmgr/tonga_thermal.c: In function 'tonga_fan_ctrl_get_fan_speed_info' So I will add "#include <asm/div64.h>" to fix the warning.
