I think that this explanation in a commit is enough for such a trivial patch.
It informs that we are fixing clang-tidy findings related to deadstores
in a block subsystem. What analysis would you want to see?
Something like "Remove deadstore assignment ret = -EINVAL in a function bio_map_user_iov" ?
I think that it will create too much of not needed overhead.
