staging: iio: Add #include guards to header files This patch adds #include guards in order to make the header files idempotent.

iio: dummy: Add virtual registers for dummy device We need a way to store events generated by iio_dummy_evgen module, in order to correctly process IRQs in iio_simple_dummy_events. For the moment, we add two registers: * id_reg - ID register, stores the source of the event * id_data - DATA register, stores the type of the event e.g echo 4 > /sys/bus/iio/devices/iio_evgen/poke2 id_reg 0x02, id_data 0x04 This means, event of type 4 was generated by fake device 2. We currently use a hardcoded mapping of virtual events to IIO events.

staging:iio:dummy Add event support + fake event generator The event generator is not very pretty but does the job and allows this driver to look a lot more like a normal driver than it otherwise would.

staging: iio_simple_dummy: fix return types The functions iio_dummy_remove(), iio_simple_dummy_events_unregister() and iio_dummy_evgen_release_irq() were changed to return void instead of int.
