netfilter: nf_tables: simplify the basic expressions' init routine
Some basic expressions are built into nf_tables.ko, such as nft_cmp, nft_lookup, nft_range and so on. But these basic expressions' init routine is a little ugly, too many goto errX labels, and we forget to call nft_range_module_exit in the exit routine, although it is harmless. Acctually, the init and exit routines of these basic expressions are same, i.e. do nft_register_expr in the init routine and do nft_unregister_expr in the exit routine. So it's better to arrange them into an array and deal with them together. Signed-off-by: Liping Zhang <zlpnobody@gmail.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
