Definitions sets const:

grep "static const" drivers/crypto/s5p-sss.c

static const struct samsung_aes_variant s5p_aes_data = {
static const struct samsung_aes_variant exynos_aes_data = {
static const struct samsung_aes_variant exynos5433_slim_aes_data = {

so it is not needed at struct declaration, or am I missing something ?
