Subject[PATCH 10/15] iio: ti_am335x_adc: Also clear threshold event when clearing overrun event
Date
From: Russ Dill <Russ.Dill@ti.com>

When an overrun occurs, the FIFO is cleared. If a FIFO threshold event
was pending, the data is now gone. Clear the threshold event when
handling an overrun (or underflow).
