Subject: [PROBLEM] gpio: hog: requesting hog failed
Date: Thu, 8 Oct 2015 14:29:47 +0200 [thread overview]
Message-ID: <561661BB.70207@aksignal.cz> (raw)
Hi everybody,
I've just tried new gpio hog functionality, but maybe I misunderstand something
or I'm doing something wrong?
Can someone help me with it, please?
Thanks, Jiri.
Here is dmesg:
