The iio_triggered_buffer_setup_ext() was changed by commit15097c7a1a("iio: buffer: wrap all buffer attributes into iio_dev_attr") to silently expect that all attributes given in buffer_attrs array are device-attributes. This expectation was not forced by the API - and some drivers did register attributes created by IIO_CONST_ATTR(). The added attribute "wrapping" does not copy the pointer to stored string constant and when the sysfs file is read the kernel will access to invalid location. Change the IIO_CONST_ATTRs from the driver to IIO_DEVICE_ATTR in order to prevent the invalid memory access.
