Routine Description:
DriverEntry initializes the driver and is the first routine called by the
system after the driver is loaded.
Parameters Description:
DriverObject - represents the instance of the function driver that is loaded
into memory. DriverEntry must initialize members of DriverObject before it
returns to the caller. DriverObject is allocated by the system before the
driver is loaded, and it is released by the system after the system unloads
the function driver from memory.
RegistryPath - represents the driver specific path in the Registry.
The function driver can use the path to store driver related data between
reboots. The path does not store hardware instance specific data.
Return Value:
STATUS_SUCCESS if successful,
STATUS_UNSUCCESSFUL otherwise.
