From c8515294a31ec63536eb1a2ba7a38797435dda4f Mon Sep 17 00:00:00 2001 From: Jingoo Han Date: Tue, 29 May 2012 15:07:25 -0700 Subject: [PATCH] backlight: tosa_lcd: use devm_ functions The devm_ functions allocate memory that is released when a driver detaches. This patch uses devm_kzalloc of these functions.
