We get a few warnings when building kernel with W=1: drivers/gpu/drm/amd/amdgpu/../powerplay/hwmgr/fiji_hwmgr.c:1633:9: warning: no previous prototype for 'fiji_get_voltage_index' [-Wmissing-prototypes] drivers/gpu/drm/amd/amdgpu/../powerplay/hwmgr/fiji_hwmgr.c:5412:5: warning: no previous prototype for 'fiji_check_states_equal' [-Wmissing-prototypes] drivers/gpu/drm/amd/amdgpu/../powerplay/hwmgr/fiji_thermal.c:424:5: warning: no previous prototype for 'tf_fiji_thermal_setup_fan_table' [-Wmissing-prototypes] ....
In fact, these functions are only used in the file in which they are declared and don't need a declaration, but can be made static. So this patch marks these functions with 'static'.
