From 2ab3a749eb14c96eaf453afe6e678c9c1dab1637 Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Tue, 5 Mar 2013 09:06:58 +0100 Subject: [PATCH] gpio-ich: Fix value returned by ichx_gpio_request Per Documentation/gpio.txt, gpio_request callbacks should return 0 on success or a negative value on error. So it is not clear what was meant by letting ichx_gpio_request return 1 in some cases, nor how a caller would interpret it. Align the code with the comment above it and consider pins as available by default.
