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(). Signed-off-by: liu chuansheng <chuansheng.liu@intel.com> --- sound/soc/soc-core.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-)
