[PATCH v2 10/10] iio: humidity: hts221: move drdy enable logic in hts221_trig_set_state()

From: Lorenzo Bianconi <hidden>
Date: 2017-07-17 17:39:05
Also in: linux-iio
Subsystem: hts221 temperature-humidity iio driver, iio subsystem and drivers, the rest · Maintainers: Lorenzo Bianconi, Jonathan Cameron, Linus Torvalds

Possibly related (same subject, not in this thread)

Move data-ready configuration in hts221_buffer.c since it is only related
to trigger logic
