Revision 1d1dc5e83f3299c108a4e44d58cc4bfef48c876a authored by Stefan Richter on 09 December 2008, 23:20:38 UTC, committed by Stefan Richter on 10 December 2008, 11:45:34 UTC
There is a DMA map/ unmap imbalance whenever a block write request packet is sent and then dequeued with ohci_cancel_packet. The latter may happen frequently if the AR resp tasklet is executed before the AT req tasklet for the same transaction. Add the missing dma_unmap_single. This fixes https://bugzilla.redhat.com/show_bug.cgi?id=475156 Reported-by: Emmanuel Kowalski Tested-by: Emmanuel Kowalski Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
