From 57370aed40bfb8bfd2daab2eddbdc4faa459e784 Mon Sep 17 00:00:00 2001 From: Sylwester Nawrocki Date: Fri, 13 Jul 2012 18:03:15 +0900 Subject: [PATCH] ARM: S3C24XX: Free the backlight gpio requested in Mini2440 board code The backlight gpio must not be left requested in the board code, otherwise s3c24xx_led driver can't successfully claim it. So request the backlight gpio, configure it to proper state and gpio_free right away. This change is required for converting the s3c24xx_led driver to the gpiolib API.
