4.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Andreas Klinger ak@it-klinger.de
commit 511051d509ec54642dd6d30fdf2caa33c23619cc upstream.
Functions for triggered buffer support are needed by this module. If they are not defined accidentally by another driver, there's an error thrown out while linking.
Add a select of IIO_BUFFER and IIO_TRIGGERED_BUFFER in the Kconfig file.
