![]() 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.
