[PATCH 06/11] staging:iio:ad7887: Do not return error code in interrupt handler

[Lars-Peter Clausen <lars@xxxxxxxxxx>]

The interrupt handler should only ever return one of the three irqreturn_t
constants and not an error code. Also make sure to always call
iio_trigger_notify_done before leaving the trigger handler.
