The check for a valid ptr in ddb_io->dma isn't really necessary since only
devices that do data transport using DMA are supported by the driver, and
all previous initialisation code (through input_init(), output_init() and
dma_init(), has_dma is always true as it's set in ddb_probe() during
driver load) guarantees the ptr is set.
As a side effect, this silences these sparse warnings (albeit them being
false positives as ddb_io->dma won't change in these functions so the
condition always equals to the same result):
