From: Wolfram Sang Date: Tue, 9 Jan 2018 11:35:53 +0000 (+0100) Subject: gpio: correct docs about return value of gpiod_get_direction X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=94fc73094abe47;p=openwrt%2Fstaging%2Fblogic.git 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.
