Normal buffer updates take\ninfo_exist_lock followed by mlock in iio_update_buffers().\n\nHowever, iio_device_unregister() disables and deactivates all buffers\nwithout taking mlock. This can invalidate buffer state, including\nactive_scan_mask, while a buffer-mode claim is held.\n\nTake mlock in iio_disable_all_buffers() so that unregister honors the\nmode-claim lifetime guarantee. The info_exist_lock -> mlock ordering\nmatches iio_update_buffers()."
