dmaengine: pxa_dma: fix initial list move
Since the commit to have an allocated list of virtual descriptors was reverted, the pxa_dma driver is broken, as it assumes the descriptor is placed on the allocated list upon allocation. Fix the issue in pxa_dma by making an allocated virtual descriptor a singleton. Fixes: 8c8fe97b2b8a ("Revert "dmaengine: virt-dma: don't always free descriptor upon completion"") Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: Vinod Koul <vinod.koul@intel.com>
