[PATCH v2 00/33] staging: comedi: dt9812: cleanup driver

[H Hartley Sweeten]

This comedi driver is for a USB device and should be using the
comedi (*auto_attach) mechanism to attach to the device. Currently
the driver is a bit of a mess has a huge disconnect between the
loading of the usb_driver and the attaching of the comedi_device.
Right now this driver will even allow attaching to the comedi_device
even if the usb device is not attached to the system.

This series cleans up the driver and moves all the USB (*probe)
functionality into the comedi (*auto_attach) and the USB (*disconnect)
into the comedi (*detach). This ensures that a usb device is attached
before the comedi core does the (*auto_attach) to attach to the device.
This also allows consolidating all the private data into one struct
and makes the driver a lot easier to understand.
