Refcounting in dsound

[Paul Vriens]

Hi, 

while going through some leftover TRACE's of the Interlocked cleanup, I
found the following refcounting in dsound/buffer.c and dsound.c:

dsound/buffer.c:                        This->buffer->ref--;
dsound/buffer.c:                This->buffer->ref--;
dsound/dsound.c:        dsb->buffer->ref++;

Is there a need to clean (i.e. use Interlocked*) this up?

Cheers,

Paul.
