It will be freed by stack in bss_release(). Driver don't need to worry about it. In mwifiex driver, we use the private area just to store band information(u8). We don't allocate memory explicitly and store it's pointer in bss->priv. Hence we don't have any cleanup work to do in free_priv handler. Currently we try to free the allocated private area in free_priv handler which is not correct. This patch removes unnecessary free_priv handler.
