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

[Stephen Rothwell]

Hi all,

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

  drivers/dma/mcf-edma.c

between commit:

  0a46781c89de ("dmaengine: mcf-edma: Fix a potential un-allocated memory access")

from Linus' tree and commit:

  923b13838892 ("dmaengine: mcf-edma: Use struct_size()")

from the dmaengine 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.
