We get a few warnings when building kernel with W=1: drivers/gpu/drm/amd/amdgpu/amdgpu_pll.c:113:6: warning: no previous prototype for 'amdgpu_pll_compute' [-Wmissing-prototypes] drivers/gpu/drm/amd/amdgpu/cz_smc.c:38:10: warning: no previous prototype for 'cz_get_argument' [-Wmissing-prototypes] drivers/gpu/drm/amd/amdgpu/cz_smc.c:302:5: warning: no previous prototype for 'cz_smu_start' [-Wmissing-prototypes] ....
In fact, these functions are declared in drivers/gpu/drm/amd/amdgpu/atombios_i2c.h drivers/gpu/drm/amd/amdgpu/amdgpu_pll.h drivers/gpu/drm/amd/amdgpu/cz_dpm.h drivers/gpu/drm/amd/amdgpu/vi_dpm.h. So this patch adds missing header dependencies.
