107	Routine Description:
108
109	This routine is used to read back various registry values.
110
111	Arguments:
112
113	HwDeviceExtension
114	Supplies a pointer to the miniport's device extension.
115
116	Context
117	Context value passed to the get registry parameters routine.
118	If this is not null assume it's a ULONG* and save the data value in it.
119
120	ValueName
121	Name of the value requested.
122
123	ValueData
124	Pointer to the requested data.
125
126	ValueLength
127	Length of the requested data.
128
129	Return Value:
130
131	If the variable doesn't exist return an error,
132	else if a context is supplied assume it's a PULONG and fill in the value
133	and return no error, else if the value is non-zero return an error.
