Normal buffer updates take info_exist_lock followed by mlock in iio_update_buffers().</p> <p>However, iio_device_unregister() disables and deactivates all buffers without taking mlock. This can invalidate buffer state, including active_scan_mask, while a buffer-mode claim is held.</p> <p>Take mlock in iio_disable_all_buffers() so that unregister honors the mode-claim lifetime guarantee.
