From 869b5567e12f63ea7407f81728ca87f8c0abbfdb Mon Sep 17 00:00:00 2001 From: Dexuan Cui Date: Tue, 14 Nov 2017 06:53:32 -0700 Subject: vmbus: unregister device_obj->channels_kset Without the patch, a device can't be thoroughly destroyed, because vmbus_device_register() -> kset_create_and_add() still holds a reference to the hv_device's device.kobj.
