Simply breaking out this hunk reduces the stack-frame use by 500 Bytes, preventing the following compiler warning: drivers/gpu/drm/amd/amdgpu/../display/dc/dml/calcs/dce_calcs.c:3285:6: warning: stack frame size (1384) exceeds limit (1024) in 'bw_calcs' [-Wframe-larger-than] bool bw_calcs(struct dc_context *ctx, ^ 1 warning generated. This resolves the issue and takes us one step closer towards a successful allmodconfig WERROR build.
