We get 3 warnings when building kernel with W=1: drivers/gpu/drm/amd/amdgpu/../powerplay/hwmgr/pp_acpi.c:29:6: warning: no previous prototype for 'acpi_atcs_functions_supported' [-Wmissing-prototypes] drivers/gpu/drm/amd/amdgpu/../powerplay/hwmgr/pp_acpi.c:47:6: warning: no previous prototype for 'acpi_atcs_notify_pcie_device_ready' [-Wmissing-prototypes] drivers/gpu/drm/amd/amdgpu/../powerplay/hwmgr/pp_acpi.c:61:5: warning: no previous prototype for 'acpi_pcie_perf_request' [-Wmissing-prototypes] In fact, these functions are declared in drivers/gpu/drm/amd/powerplay/inc/pp_acpi.h, so this patch adds missing header dependencies.
