Please see commit: > > 5f533aeb gpio: Modify common gpio.h to more closely match Linux This is generic gpio cleanup but I don't think this is the same thing. I think you should get some warnings for fdtdec compilation around missing gpio_request declaration or you include gpio.h in any other header file which is in fdtdec.c/h.
