->dmacount tracks the sequence number of active descriptors. It is written to the DMACOUNT register to update the channel's view of pending descriptors in the chain. The register is 16-bits so ->dmacount should be unsigned and 16-bit as well. Also modify ->desccount to maintain alignment. This was never a problem in practice because we never compared dmacount values, but this is a bug waiting to happen.
