I haven't see any fixes for this, although I could have easily
missed a patch.

The patch below should fix these build errors.

---
From: Randy Dunlap <rdunlap@xxxxxxxxxxxxx>

Fix build errors in iio/rockchip_saradc by adding selects
to drivers/iio/adc/Kconfig.

Fixes these build errors:

ERROR: modpost: "devm_iio_triggered_buffer_setup"

ERROR: modpost: "iio_trigger_notify_done"
[drivers/iio/adc/rockchip_saradc.ko] undefined!
ERROR: modpost: "iio_push_to_buffers"
