From 2f8d16a996da0b9be2536994aa7a825418364471 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Fri, 9 Mar 2007 19:34:19 +0900 Subject: [PATCH] devres: release resources on device_del() Some platform devices are driven without driver attached, so managed resources can be acquired without driver attached. Make sure such resources are released by calling devres_release_all() in device_del().
