The 'context' passed to comedi_auto_config() is currently an unsigned long value. This value is passed to the (*auto_attach)() function of a comedi driver. Currently none of the comedi drivers use the 'context'. The only callers of comedi_auto_config() are the two inline wrappers comedi_pci_auto_config() and comedi_usb_auto_config(). Both of these pass a 'context' of 0. Change the 'context' to a const void * and rework the auto_config code and the pci/usb drivers so that the 'context' passed is the struct {pci,usb}_device_id * that is passed to the {pci,usb}_driver (*probe)() function.

I'm not sure what you're planning to do with this, but maybe it would be better to pass the `driver_data` from the `struct pci_device_id` or the `driver_info` from the `struct usb_device_id` and change the type of the context to `kernel_ulong_t`?
