commit 217afe63ccf445fc220e5ef480683607b05c0aa5 upstream.
IIO triggered buffer depends on IIO buffer which is missing from Kconfig file. This should go unnoticed most of the time because there's a chance something else has already enabled buffers. In some rare cases though one might experience kbuild warnings about unmet direct dependencies and build failures due to missing symbols.
Fix this by selecting IIO_BUFFER explicitly.
