There are two cases\nwhere private data is not created:\n\n1. The control is a SYSTEM control, so an ALSA control is not created.\n\n2. The codec driver has registered a control_add() callback that\n   hides the control, so wm_adsp_control_add() is not called.\n\nWhen cs_dsp_remove destroys its control list it calls\nwm_adsp_control_remove() for each control. But wm_adsp_control_remove()\nwas attempting to cleanup the private data pointed to by cs_ctl->priv\nwithout checking the pointer for NULL."
