Thanks for the review. Since both sta_set_link_sinfo() and sta_set_sinfo() use this helper,
I introduced it to avoid duplicating the BSS configuration lookup logic in both callers.
I can remove it if you prefer.

Yes, you are right. The sdata->bss NULL check is unnecessary here.
I will remove it and send the next version.
