<div class='commit-subject'>spi: omap2-mcspi: Use dma_request_chan() for requesting DMA channel</div><div class='commit-msg'>With the new dma_request_chan() the client driver does not need to look for
the DMA resource and it does not need to pass filter_fn anymore.
By switching to the new API the driver can now support deferred probing
against DMA.
