Subject: iio: dht11 broken

Hi!

Staring with 3.12 gpiolib refuses to set an GPIO used as IRQ into output mode.
see commit d468bf9e (gpio: add API to be strict about GPIO IRQ usage)
The dht driver does this and is therefore not functional.
As the dht11 driver got merged in 3.13 there is a high chance that it never worked.

Harald, are you aware of this issue?

Thanks,
//richard
