Subject: [PATCH v2 07/23] gpio: sysfs: rename gpiochip registration functions
Date: Mon, 4 May 2015 17:10:32 +0200 [thread overview]
Message-ID: <1430752248-15401-8-git-send-email-johan@kernel.org> (raw)
In-Reply-To: <1430752248-15401-1-git-send-email-johan@kernel.org>
Rename the gpio-chip export/unexport functions to the more descriptive
names gpiochip_sysfs_register and gpiochip_sysfs_unregister.
Signed-off-by: Johan Hovold <johan@kernel.org>
