I think it isn't always required basically. However, for this case, I can't find
the author to know if we can remove the statements. There is a delay to
make sure these read operations can get correct values, so I suggest to have
similar changes like 6c75eab0417b9e5b05a18dbfc373e27a8ef876d8 you mentioned if
we really want this patch.
