152 static int adis16460_set_freq(struct iio_dev *indio_dev, int val, int val2)
153 {
154 struct adis16460 *st = iio_priv(indio_dev);
155 unsigned int t;
^^^^^^^^^^^^^^
156
157 t = val * 1000 + val2 / 1000;
158 if (t <= 0)
^^^^^^
Unsigned is not less than zero.
```
The types of `val` && `val2` are obtained from the IIO `write_raw` hook, so
userspace can provide negative values, which can cause weird behavior after
conversion to unsigned.
This patch changes the sign of variable `t` so that -EINVAL will be
returned for negative values as well.
