Subject: [PATCH 1/2] gpio: correct docs about return value of gpiod_get_direction
Date: Tue, 9 Jan 2018 12:35:53 +0100 [thread overview]
Message-ID: <20180109113554.4337-1-wsa@the-dreams.de> (raw)
From: Wolfram Sang <wsa+renesas@sang-engineering.com>
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.
