linux-next: manual merge of the slave-dma tree with Linus' tree

Hi Vinod,

Today's linux-next merge of the slave-dma tree got a conflict in:

  drivers/dma/dmatest.c

between commit:

  6454368a804c ("dmaengine: dmatest: Abort test in case of mapping error")

from Linus' tree and commit:

  361deb7243d2 ("dmaengine: dmatest: wrap src & dst data into a struct")

from the slave-dma tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.

Stephen Rothwell
