A couple of fields in a data structure, which is used by the driver only,
were not initialized properly during the driver's setup.
The primary issue with this bug was that channel->wr_buf_size remained zero,
so calls to dma_sync_single_for_cpu() took place with zero size, and
consequently did nothing.
This had a rather minimal practical impact, because
(a) these calls are NOPs on Intel/AMD platforms, as well as other platforms
with coherent cache, and
(b) it's extremely rare that any cache line would survive between two reads
from a given DMA buffer
Hence no significant practical difference is expected with this patch.
