From 7428fff20494935b4ce767d7c80de077e8d1d745 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Sat, 15 Jan 2011 17:55:45 +0100 Subject: ARM: pxa: PalmTE2: Use gpio arrays in backlight init Use gpio_request_array() / gpio_free_array() in backlight init and exit functions. This makes the code cleaner and less error prone.
