Christian Lamparter ab703f818a dmaengine: dw: lazy allocation of dma descriptors ... This patch changes the driver to allocate DMA descriptors when needed. This stops memory resources to be wasted and letting them sit idle in the free_list structure when the device doesn't need it... This also solves the problem, that a driver has to guess the number of how many descriptors it needs to allocate in advance. Currently, the dma engine will just fail when put under load by sata_dwc_460ex.
