ddi_get_driver_private()
dip
Pointer to device information structure to get

ddi_set_driver_private()
dip

data
Data area address to set.
The ddi_get_driver_private() function returns the address of the device's
private data area from the device information structure pointed to by
dip.
The ddi_set_driver_private() function sets the address of
the device's private data area in the device information structure pointed
to by dip with the value of data.
The ddi_get_driver_private() function returns the contents of
devi_driver_data. If ddi_set_driver_private() has not been
previously called with dip, an unpredictable value is returned.
