Thanks!

Will apply and queue for v3.17.
I also converted the MANUF definition a few lines above:

-#define MANUF( manuf, name ) { 0x##manuf,
sizeof(__prods_##manuf) / sizeof(struct zorro_prod_info),
__manufstr_##manuf, __prods_##manuf },
+#define MANUF( manuf, name ) { 0x##manuf,
ARRAY_SIZE(__prods_##manuf), __manufstr_##manuf, __prods_##manuf },
