[PATCH 24/51] DMA-API: dma: pl330: add dma_set_mask_and_coherent() call

2013-09-23 Thread Russell King 
The DMA API requires drivers to call the appropriate dma_set_mask()
functions before doing any DMA mapping.  Add this required call to
the AMBA PL08x driver.

   ^--- copy and paste error - should of course be PL330

Fixed, thanks.
