My latest (v2) version of the patch deletes the check.

But doing that is dependent on the s3c-pl330 going away and
being replaced by the dmaengine driver, else I think we shall try to
keep the check (I will have to make it work without
dereferencing the amba_device or it will break).

Is it your plan to replace s3c-pl330 with the drivers/dma/pl330.c
driver, so I can safely delete this code?

Thanks,
