From 94fc73094abe4798be8d4af60227be41a6dc3be8 Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Tue, 9 Jan 2018 12:35:53 +0100 Subject: gpio: correct docs about return value of gpiod_get_direction The use of the GPIOF_* flags is deprecated, so don't advertise them here. Document the plain numbers for now until we have a better solution.
