staging:iio:addac:adt7316 replace abuse of buffer events.
Currently squashed the fault condition from external temperature sensor - lots of other issues to be fixed with this driver which obeys almost no elements of the abi. V2: removed a couple of usused variables that sparse found. Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
