Subject: linux-next: manual merge of the dmaengine tree with the driver-core
 tree

Hi all,

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

  drivers/dma/idxd/sysfs.c

between commit:

  fc7a6209d571 ("bus: Make remove callback return void")

from the driver-core tree and commit:

  d9e5481fca74 ("dmaengine: dsa: move dsa_bus_type out of idxd driver to standalone")

from the dmaengine tree.

I fixed it up (the latter moved the code updtaed by the former,
so I added the following merge fix patch) 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.
