iio: dht11 Updates

[Richard Weinberger]

Please see my current patches for your driver.
As discussed in an earlier mail I'm testing with the DHT22 sensor only.
With the IRQ changes I see 84 edges.

I have also a question on your driver. Why you increment
DHT11_DATA_BIT_LOW/timeres by one in the ambiguity check?

        threshold = DHT11_DATA_BIT_HIGH / timeres;
        if (DHT11_DATA_BIT_LOW/timeres + 1 >= threshold)
                pr_err("dht11: WARNING: decoding ambiguous\n");

Thanks,
//richard
