We get 2 warnings when building kernel with W=1: drivers/gpu/drm/amd/amdgpu/amdgpu_ttm.c:985:5: warning: no previous prototype for 'amdgpu_ttm_init' [-Wmissing-prototypes] drivers/gpu/drm/amd/amdgpu/amdgpu_ttm.c:1092:6: warning: no previous prototype for 'amdgpu_ttm_fini' [-Wmissing-prototypes] In fact, both functions are declared in drivers/gpu/drm/amd/amdgpu/amdgpu_ttm.c, but should be declared in a header file, thus can be recognized in other file. So this patch moves the declarations into drivers/gpu/drm/amd/amdgpu/amdgpu.h.
