4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Lars-Peter Clausen <lars@xxxxxxxxxx>
commit be94a6f6d488b4767662e8949dc62361bd1d6311 upstream.
Add missing break in iio_simple_dummy_write_event_config() for the voltage
threshold event enable attribute. Without this writing to the
in_voltage0_thresh_rising_en always returns -EINVAL even though the change
was correctly applied.
Fixes: 3e34e650db197 ("iio: dummy: Demonstrate the usage of new channel types")
