Merge branch 'topic/defer_probe' of git://git.infradead.org/users/vkoul/slave-dma...

The following branch/patch is a dependency for my "ASoC: dmaengine:
support deferred probe for DMA channels". If you could pull the branch
below into your topic/dma, then merge my ASoC patch, that would be
great. I would then like to merge your topic/dma into the Tegra tree as
a baseline for the Tegra conversion to the standard DMA DT bindings.

Vinod has confirmed this his topic/defer_probe branch is stable, and
won't be rebased:
