    ide-cd: use common completion path for DMA requests in cdrom_newpc_intr() · 4a3d8cf4
    Bartlomiej Zolnierkiewicz authored
    Use the following facts:
    - rq->nr_sectors should now be always equal to (non-zero)
      rq->hard_nr_sectors for fs requests
    - REQ_TYPE_ATA_PC requests have never bio attached to them
    - rq->hard_nr_sectors == 0 for REQ_TYPE_ATA_PC requests
    - DMA is used only for fs, pc and REQ_TYPE_ATA_PC requests
    - 'uptodate' is ignored for pc requests ('rc == 0' case)
    and use the common completion path also for DMA requests.
    There should be no functional changes caused by this patch
