153
154	This routine is used to read back various registry values.
155
156	Arguments:
157
158	HwDeviceExtension
159	Supplies a pointer to the miniport's device extension.
160
161	Context
162	Context value passed to the get registry parameters routine.
163	If this is not null assume it's a ULONG* and save the data value in it.
164
165	ValueName
166	Name of the value requested.
167
168	ValueData
169	Pointer to the requested data.
170
171	ValueLength
172	Length of the requested data.
173
174	Return Value:
175
176	If the variable doesn't exist return an error,
177	else if a context is supplied assume it's a PULONG and fill in the value
178	and return no error, else if the value is non-zero return an error.
