> 
> Commit 6e2e98d6775b ("event/dlb2: support independent enqueue")
> updated the avx512 code path with support for the event, or "qe" weights.
> However, the SSE code path looks to have been missed in the update.
> Update the SSE "build_hcws" function to match the changes made to the
> AVX-512 version.
