Hi Jaehee,
If I recall it correctly, Dan Carpenter suggested to remove this empty
function.
When developers remove lines of code from a function which becomes empty
after the removals, they also remove the resulting empty function and
delete all the calls (if there are any left) at the same time.
Thanks,
Fabio M. De Francesco
