When config option IRQ_DOMAIN is unset, compiling the file
'drivers/gpu/drm/amd/amdgpu/amdgpu_irq.c' fails:
CC drivers/gpu/drm/amd/amdgpu/amdgpu_irq.o

Adding the functions stubs in the header file so it compiles cleanly.
Maybe the drm driver 'amdgpu' should select the config option IRQ_DOMAIN
if it cannot work without it. But I don't know if that's necessary.
