Subject: [PATCH] iio: dummy: events: Add missing break
Git-commit: be94a6f6d488b4767662e8949dc62361bd1d6311
Patch-mainline: v4.14-rc6
References: bsc#1051510

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.
