Subject: dmaengine: omap-dma: Use pointer to omap_sg in slave_sg setup's loop
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=cb7958dfa9bc4a69f94eaa8bbc9d21a291a2a560;p=linux-beck.git

dmaengine: omap-dma: Use pointer to omap_sg in slave_sg setup's loop

Instead of accessing the array via index, take the pointer first and use
it to set up the omap_sg struct.
