From 28e9cc8056bddce5863e455028369cd3b01ef941 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Tue, 31 Jul 2012 05:21:36 -0300 Subject: [PATCH] [media] drivers/media/radio/radio-si4713.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.
