From 06c96f189bf94448779db66944836a827517d6c9 Mon Sep 17 00:00:00 2001 From: Jingoo Han Date: Tue, 29 May 2012 15:07:22 -0700 Subject: [PATCH] backlight: corgi_lcd: use devm_ functions The devm_ functions allocate memory that is released when a driver detaches. This patch uses devm_kzalloc of these functions.
