[PATCH V2 5/6] dmaengine: tegra-apb: Update driver to use GFP_NOWAIT

Show all headers | View raw

The tegra20-apb-dma driver currently uses the flag GFP_ATOMIC when
allocating memory for structures used in conjunction with the DMA
descriptors. It is preferred that dmaengine drivers use GFP_NOWAIT
instead and so the emergency memory pool will not be used by these
drivers.
