From: Arnd Bergmann <arnd@xxxxxxxx>
When CONFIG_DYNAMIC_DEBUG is disabled altogether, calling
_dynamic_func_call_no_desc() does not work:
drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_svm.c: In function 'svm_range_set_attr':
drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_svm.c:52:9: error: implicit declaration of function '_dynamic_func_call_no_desc' [-Werror=implicit-function-declaration]
52 | _dynamic_func_call_no_desc("svm_range_dump", svm_range_debug_dump, svms)
| ^~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_svm.c:3564:9: note: in expansion of macro 'dynamic_svm_range_dump'
3564 | dynamic_svm_range_dump(svms);
| ^~~~~~~~~~~~~~~~~~~~~~
Add a compile-time conditional in addition to the runtime check.
Fixes: 8923137dbe4b2 ("drm/amdkfd: avoid svm dump when dynamic debug disabled")
