Subject: libext2fs: remove useless test and assignment in strtohashbuf()
X-Git-Tag: v1.44.0-rc1~45

libext2fs: remove useless test and assignment in strtohashbuf()

On transformation of str to hash, computed value is initialised before
first byte modulo 4. But it is already initialised before entering loop
and after processing last byte modulo 4. So the corresponding test and
initialisation could be removed.
