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.

The Onda v975w tablet contains an accelerometer that's advertised over
ACPI as SMO8500. This device is however a KXCJ9 accelerometer as
can be seen in the Windows driver's INF file, and from the etching on
the chipset ("KXCJ9 41566 0414").
This patch also removes the attempt to get the IRQ for the "data ready"
signal, as it does not seem to be supported by this device on this
platform.

Remove the private data member 'ai_sample_count' and use the comedi_async
'scans_done' member to detect the analog input end-of-acquisition.
Move the EOA check so it happens after adding the samples from the current
urb to the async buffer. This prevents the unnecessary resubmit of the urb
when the EOA occurs.

Introduce a new member to comedi_async to count the number of scans completed.
This member is cleared by comedi_buf_reset() along with the other comedi_async
members. It is incremented in comedi_inc_scan_progress() when the end of scan
is detected.
This member will be used to clean up the scan counting in the comedi drivers.

Wake queue in the dwIsr loop of device_intr instead of device_tx_srv.
This fixes an issue when ISR_TXDMA0 or ISR_AC0DMA does not occur
device_tx_srv is not called and the queue gets stuck in stopped
condition.
On test if the queue is stuck another MACvTransmitAC0 or MACvTransmit0
in vnt_tx_packet will clear it.
Check on vif that both buffers are available and the queue is stopped.
