We need distinguish the following two situations in various SPI APIs: - given chip select num is invalid - given chip select num is valid, but no device is attached Currently -ENODEV is returned for both cases. For the first case, it's more reasonable to return -EINVAL instead of -ENODEV for invalid chip select numbers.
