From 901b74a3c4044a07c7149365aa9c4eaa6c71964b Mon Sep 17 00:00:00 2001 From: Jingoo Han Date: Thu, 7 Mar 2013 18:39:04 -0800 Subject: [PATCH] leds: renesas: set gpio_request_one() flags param correctly The gpio_request_one() flags parameter was set to: GPIOF_DIR_OUT | !!brightness GPIOF_DIR_OUT and GPIOF_DIR_IN are defined as below: GPIOF_DIR_OUT (0 << 0) GPIOF_DIR_IN (1 << 0) So, when '!!brightness' is 1, the gpio pin can be set as input, instead of output. To prevent this problem, GPIOF_OUT_INIT flags should be used when using gpio_request_one().
