From d3bf1561253383a3dbcc40afdb2b039d56093a3e Mon Sep 17 00:00:00 2001 From: Chuansheng Liu Date: Wed, 26 Dec 2012 00:57:32 +0800 Subject: [PATCH] ASoC: core: fix the memory leak in case of remove_aux_dev() When probing aux_dev, initializing is as below: device_initialize() device_add() So when remove aux_dev, we need do as below: device_del() device_put() Otherwise, the rtd_release() will not be called. So here using device_unregister() to replace device_del(), like the action in soc_remove_link_dais().
