Now that the SPDX tag is in all comedi files, that identifies the
license in a specific and legally-defined manner. So the extra GPL text
wording can be removed as it is no longer needed at all.
This is done on a quest to remove the 700+ different ways that files in
the kernel describe the GPL license text. And there's unneeded stuff
like the address (sometimes incorrect) for the FSF which is never
needed.
No copyright headers or other non-license-description text was removed.

It's good to have SPDX identifiers in all files to make it easier to
audit the kernel tree for correct licenses.
Update the drivers/staging/comedi files files with the correct SPDX
license identifier based on the license text in the file itself. The
SPDX identifier is a legally binding shorthand, which can be used
instead of the full boiler plate text.
This work is based on a script and data from Thomas Gleixner, Philippe
Ombredanne, and Kate Stewart.

This patch simplify a trivial if-return sequence. Possibly combine with
a preceding function call.

Rewrite the "Devices:" line in the comedi "driver" comment to conform to
the usual comedi format for this line. The line should be a
comma-separated list where the first item is in the following format:
[Manufacturer] BOARD-NAME (comedi-board-name)
The "[Manufacturer]" and/or "(comedi-board-name)" parts may be omitted
from following items, in which case the parts from the preceding item
are used. The "Devices:" line may be continued continued over several
lines by using one or more spaces at the start of each continuation line
(not counting the space after the "*" in the block comment).

Most of the comedi drivers that provide readback for write only subdevices now
use the comedi core comedi_alloc_subdev_readback() helper to allocate the subdevice
'reaback' member instead of using some member in their private data. These drivers
also hook up the (*insn_read) callback to the comedi_readback_insn_read() helper to
provide the readback.
Have the core automatically hook up the (*insn_read) callback after allocating the
memory if the driver has not already hooked it up to a private function.

Use the new comedi_subdevice 'readback' member and the core provided
(*insn_read) for the readback of the analog output subdevice channels.
Remove the unused private data and its allocation.

This board is currently supported by the poc driver. That driver used
to support a number of simple boards but now only provides support for
the DAC02 board.
Introduce a new comedi driver specifically for the DAC02 board. This
allows cleaning up all the cruft.
