Dht11 driver problem
Hi,
I loaded the DHT11 driver with current linus tree on my BeagleBone black, Interfaced DHT11.
While reading the DHT11 data from sys file system, its failing.
dmesg: gpio-30 (humidity_sensor): _gpiod_direction_output_raw: tried to set a GPIO tied to an IRQ as output
Its failing because in probe function we register gpio as irq and after that while read raw making same pin as output.
Is there any updated patches to avoid this problem..?
One more thing is that this driver is not available in IIO git tree.
Any help..?

Master branch is hardly ever used. Try togreg branch for the latest. Not cgit makes it
harder than it should be to browse particular branches so you may not be looking at what you think you are! It has gotten me a few times...
