This back pointer is no longer needed by the driver. Remove it.

Pass the comedi_device pointer (the urb context) to this function
instead of the private data pointer.
Use a local variable for the urb pointer that is setup and submitted.
Remove the sanity check of the private data. This function can only
get called if the allocation was successful during the attach.

Most of these are just function trace noise. The rest report errors
that the user can't do anything about so they amount to added noise.

These defines are only used to index the dev->subdevices array
during the attach. It's cleaner to just open-code the values.

Rename the local variables to the comedi "norm".
The comedi_subdevice in this function is actually the dev->write_subdev
that was initialized in the attach. Use that instead of accessing the
dev->subdevices array directly.
Use dev->class_dev as the device for all dev_printk() messages.
Instead of using the 'comedidev' back pointer in the private data, use
the comedi_device 'dev' that we already have.

This function is only called by usbdux_auto_attach(), absorb it.
Also, there is no reason to down/up the semaphore during the attach.
None of the subdevices are functioning yet so there are no commands
being sent to the usb device.

Rename the local variable used for the device private data.
Move the setting of the device private data 'comedidev' to the
(*auto_attach) where the other back pointers are set.
Tidy up the subdevice init by removing the unnecessary comments
and adding some whitespace.
Remove the unnecessary dev_info() after a sucessful attach.

This define enables printing of the 'dux_commands' that is sent to
the usb device in send_dux_commands(). This type of development
debug should not be left in the final driver.

The tidy_up() function is only called by the (*detach). That function
unlinks any running urbs and frees all the allocated urbs and buffers
used by the driver.
Rename tidy_up() to usbdux_free_usb_buffers() and move all the parts
that don't deal with the freeing of the buffers directly into the
(*detach).
Also, remove all the unnecessary clearing of the pointers. The comedi
core will kfree() the private data after calling the (*detach).
Foe aesthetic reasons, do the kfree()'ing of the buffers and urbs in
the reverse order that they were allocated.

If the comedi_driver (*auto_attach) fails, the comedi core will call
the (*detach) function to do any cleanup. It's not necessary to do
the cleanup in the (*auto_attach).

The usb_driver (*probe) calls comedi_usb_auto_config() after finding a
free slot for the static private data and doind some initial allocation
and setup. The comedi_usb_auto_config() will then call the comedi_driver
(*auto_attach).
Move all the probe/auto_attach into the comedi_driver and just have the
usb_driver call comedi_usb_auto_config(). This allows the comedi_driver
to allocate the private data and removes the need for the static array
and the semaphore that protects it.
Since all the probe/auto_attach is now handled by the comedi_driver, we
can also remove the 'attached' and 'probed' information from the private
data. The subdevice functions will only be hooked up if the usb device
has been probed and the comedi device is attached.

The usb_driver (*disconnect) calls comedi_usb_auto_unconfig() which will
call the comedi_driver (*detach). Just move all the disconnect/detach
into the comedi_driver and use comedi_usb_auto_unconfig() directly for
the (*disconnect).

The dev_dbg() during the usb_driver (*probe) is just added noise.
The dev_err() when a usb_alloc_urb() fails is not necessary. The
allocation failure will have already output a message.
