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.
