... keep ret but OR it in with its previous value:

case 8:
ret = sbi_send(port, off + 4, op, (u32 *)(data + 4));
/* fall through */
case 4:
ret |= sbi_send(port, off, op, (u32 *)data);

> /* fall through */
> case 4:
> ret = sbi_send(port, off, op, (u32 *)data);

... and merge both into a single patch.

Thanks.
