Routine Description:
This routine is used to read back various registry values.
Arguments:
HwDeviceExtension
Supplies a pointer to the miniport's device extension.
Context
Context value passed to the get registry parameters routine.
If this is not null assume it's a ULONG* and save the data value in it.
ValueName
Name of the value requested.
ValueData
Pointer to the requested data.
ValueLength
Length of the requested data.
Return Value:
If the variable doesn't exist return an error,
else if a context is supplied assume it's a PULONG and fill in the value
and return no error, else if the value is non-zero return an error.
