From 63fd0ae4b7ca60f7322341b0fbd9cda2f3d2e22d Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Mon, 30 Jul 2012 16:43:44 +0200 Subject: [PATCH] drivers/usb/host/ehci-s5p.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.
