That appears to work too, thanks.

I'll have a look at the existing tests; let's see what I come up with.

I'd expect that the correct behavior is to set pBits to NULL.
test_volume_locking() demonstrates this for volumes.

I think this patch makes sense, but could you please add a test case
as well? Ideally we'd also have similar tests for other resources
(i.e., textures, volumes, vertex buffers, index buffers) and D3D
versions (ddraw, d3d8), but that's not a strict requirement.

Minor style issue, this should be:

if (SUCCEEDED(hr))
{
...
}
