[wdmaudiodev] Bug in MSVAD sample, or misunderstanding?

In the msvad sample in the XP DDK, in basedma.cpp, the following code
exists for the FreeBuffer method:

    if ( m_pvDmaBuffer )
    {
        ExFreePool( m_pvDmaBuffer );
        m_ulDmaBufferSize = 0;
    }

Am I missing something, or should m_pvDmaBuffer be set to NULL after the
free? This has the potential of being called to free a NULL pointer,
right?

Thanks,
-Chris
