[PATCH net-next v2 2/2] net: openvswitch: Constify static struct genl_small_ops

From: Rikard Falkeborn
Date: Sun Oct 04 2020 - 19:45:22 EST


The only usage of these is to assign their address to the small_ops field
in the genl_family struct, which is a const pointer, and applying
ARRAY_SIZE() on them. Make them const to allow the compiler to put them
in read-only memory.
