Please add:

   git://git.kernel.org/pub/scm/linux/kernel/git/djbw/dmaengine.git next

to -next to replace the old async_tx.git tree.  It should be included
in the merge order after Vinod's slave dma tree at:

   git://git.infradead.org/users/vkoul/slave-dma.git next

I still expect the majority of dmaengine traffic to go through
slave-dma.git, with dmaengine.git picking up the memory-to-memory
offload specific bits.  The name change of async_tx.git to
dmaengine.git relates to the reworks needed to async_tx api which
needs replacement to fix dma mapping api violations.

Right now it only contains one patch:

    dmaengine: fix missing 'cnt' in ?: in dmatest

    Hi,
      On the latest tree my compiler has started giving the warning:

    drivers/dma/dmatest.c:575:28: warning: the omitted middle operand
in ?: will always be ?true?, suggest explicit middle op

    The following patch fixes the missing middle clause with the same
    fix that Nicolas Ferre used in the similar clauses.
    (There seems to have been a race between him fixing that and
    the extra clause going in a little later).

    I don't actually know the dmatest code/structures, nor do I own
    any hardware to test it on (assuming it needs a DMA engine);
     but this patch builds, the existing code is almost certainly
    wrong and the fix is the same as the corresponding lines above it.

    (WTH is x=y?:z legal C anyway?)
