From f072c8900c11bc91eb3fa9287bab4ce606632be5 Mon Sep 17 00:00:00 2001 From: Jingoo Han Date: Tue, 29 May 2012 15:07:25 -0700 Subject: [PATCH] backlight: tosa_bl: use devm_ functions The devm_ functions allocate memory that is released when a driver detaches. This patch uses devm_kzalloc of these functions.
