Yes. There is another drawback when GPIOs are not properly requested. It is still possible to request them from userspace although a kernel driver is using them. I am playing with the idea that the GPIO core auto-requests GPIOs which are not already requested but still set up as interrupts. -------------- next part -------------- A non-text attachment was scrubbed...
