When building with clang, there is a warning (or error when
CONFIG_WERROR is set):
drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm_helpers.c:368:21: error: variable 'old_payload' is uninitialized when used here [-Werror,-Wuninitialized]
368 | new_payload, old_payload);
| ^~~~~~~~~~~
drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm_helpers.c:344:61: note: initialize the variable 'old_payload' to silence this warning
344 | struct drm_dp_mst_atomic_payload *new_payload, *old_payload;
| ^
| = NULL
1 error generated.
This variable is not required outside of this function so allocate
old_payload on the stack and pass it by reference to
dm_helpers_construct_old_payload(), resolving the warning.
