From 426577bd8846d67b735b3a4e8926ef00abb15297 Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Mon, 4 May 2015 17:10:32 +0200 Subject: [PATCH] gpio: sysfs: rename gpiochip registration functions Rename the gpio-chip export/unexport functions to the more descriptive names gpiochip_sysfs_register and gpiochip_sysfs_unregister.
