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?
