staging: comedi: dt9812: convert to use comedi (*auto_attach)
Converting this driver to use the comedi (*auto_attach) mechanism
allows pushing the usb (*probe) into the comedi (*auto_attach) and
the usb (disconnect) into the comedi (*detach). This removes the
disconnect between the usb driver and the comedi driver. Now when
the comedi driver is attached it will always have a usb device
associated with it.
This removes the 16 usb device limitation and allows bringing all
the private data into a single struct that can be kzalloc'ed when
the comedi driver is (*auto_attached). It also allows removing the
the sanity checks that make sure a usb device is connected to the
comedi device in the helper functions.
For aesthetic reasons, add some whitespace to the subdevice init.
Also, fix the analog out subdevice. There are 2 analog output
channels available on the usb device.
