commit 9122b54f26 upstream.
Using iio_trigger_poll() can oops when multiple interrupts
happen before the first is handled.
Use iio_trigger_poll_chained() instead and use the timestamp
when processed, since it will be in theory be 2 ms max latency.
Fixes: 24ddb0e4bb ("iio: Add AS3935 lightning sensor support")
