Perhaps you can add small comment indicating its prior function:

sched_rt_do_global() was responsible for managing the RT throttling
parameters before the introduction of the fair server.

Since commit 5f6bd380c7bd ("sched/rt: Remove default bandwidth control")
sched_rt_do_global() turned obsolete but the empty helper was retained.
