Remove the final dev_info() at the end of the board attach. This is
just added noise.

Fix two issues with the analog output subdevice:
1) The raw data from the comedi core should be saved for readback
not the munged two's complement data that is written to the
hardware.
2) Avoid a possible deadlock while waiting to write the analog
output data.

Change the MODULE_DESCRIPTION to something useful instead of the
generic "Comedi low-level driver".

Use comedi_offset_munge() to munge the offset binary values from the
comedi core into the two's complement form that the hardware expects.
This removes the hard coded assumption that the analog outputs are
16-bits and instead does the munging based on the s->maxdata.

The comedi core expects the data to/from analog subdevices to be
in offset binary coding. This means that a value of '0' represents
the most negative and a value of 's->maxdata' the most positive
signal of the analog subdevice.
Many comedi drivers require the data written to the analog outputs,
or
Remove a possible deadlock while waiting to write the analog output data.
The data transfer rate for every D/A data write in this driver is 2.2us.
Wait up to 10us for the board to be ready then and return -ETIME.

This driver munges the raw data from the comedi core into its two's
complement form before writing it to the hardware. The last value
written to the hardware is saved in the private data for readback.
Since the comedi core always expects the data to be in offset binary
coding, make sure to save th
