Static analysis showed that unitialized array is being used for compare. At line 850 when a dma_mapping_error() occurs, it jumps to dma_unmap. At this point, dma_srcs has not been initialized. However, the code after dma_unmap label checks dma_srcs for a comparison and thus is comparing to random garbage in the array. Given that when dest_dma is being mapped this is the first instance of mapping DMA memory and failed, there is really nothing to be cleaned up and thus should jump to free_resources label instead.
