From ad4e1a7caf937ad395ced585ca85a7d14395dc80 Mon Sep 17 00:00:00 2001 From: Haojian Zhuang Date: Sun, 17 Feb 2013 19:42:48 +0800 Subject: gpio: fix wrong checking condition for gpio range If index++ calculates from 0, the checking condition of "while (index++)" fails & it doesn't check any more. It doesn't follow the loop that used at here. Replace it by endless loop at here. Then it keeps parsing "gpio-ranges" property until it ends.
