From: Cristina Opriceana <cristina.opriceana@gmail.com>
commit 41d903c00051d8f31c98a8136edbac67e6f8688f upstream.
Negative return values are not supported by iio_event_poll since its return type is unsigned int.
Fixes: f18e7a068a0a3 ("iio: Return -ENODEV for file operations if the device has been unregistered")
