From 0b7ca58961cd5c8c20041ffdc640775ccb7671dd Mon Sep 17 00:00:00 2001 From: Damien Cassou Date: Tue, 31 Jul 2012 18:39:18 +0200 Subject: [PATCH] drivers/video/mbx/mbxfb.c: use devm_ functions The various devm_ functions allocate memory that is released when a driver detaches. This patch uses these functions for data that is allocated in the probe function of a platform device and is only freed in the remove function.
