linux-next: manual merge of the driver-core tree with the slave-dma tree

[Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>]

Hi Greg,

Today's linux-next merge of the driver-core tree got a conflict in
drivers/dma/dw_dmac.c between commit c4cabfced23f ("dmaengine: dw_dmac:
Enhance device tree support") from the slave-dma tree and commit
463a1f8b3cee ("dma: remove use of __devinit") from the driver-core tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).
