From beb0a43f398efac87a3b9c2c6a5c5a163df50413 Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Mon, 3 May 2010 14:42:44 +0800 Subject: [PATCH] backlight: l4f00242t03: fix error handling in l4f00242t03_probe Error handling fixes: 1. In the case of kzalloc failure, simple return -ENOMEM instead of goto err. ( priv is NULL in this case ) 2. In the case of gpio_request fail for reset_gpio and data_enable_gpio, properly release resources by goto err and err2 respectively.
