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 [PATCH 1/4] iio: dht11: Add locking [PATCH 2/4] iio: dht11: IRQ fixes [PATCH 3/4] iio: dht11: Logging updates [PATCH 4/4] iio: dht11: Fix out-of-bounds read -- To unsubscribe from this list: send the line "unsubscribe linux-iio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
