From 1eddd9770f7e809228ae761ecc575f214f571e51 Mon Sep 17 00:00:00 2001 From: Jingoo Han Date: Mon, 17 Dec 2012 16:01:12 -0800 Subject: [PATCH] drivers/video/backlight/lms283gf05.c: use GPIOF_INIT flags when using devm_gpio_request_one() GPIOF_DIR_OUT and GPIOF_DIR_IN are defined as below: GPIOF_DIR_OUT (0 << 0) GPIOF_DIR_IN (1 << 0) So, when !pdata->reset_inverted is 1, the gpio pin can be set as input, instead of output. To prevent this problem, GPIOF_INIT flag should be used when using devm_gpio_request_one().
