If dma_pool_alloc() fails while constructing the list, the\ncurrent code sets buf to NULL and later dereferences it unconditionally\nat the end of the function:\n\n  buf->next = NULL;\n  buf->phys_next = 0;\n\nThis can lead to a null-pointer dereference on allocation failure.\n\nIf the failure happens after part of the descriptor chain has already\nbeen allocated and DMA-mapped, the partially constructed chain also\nneeds to be released.\n\nFix this by terminating the partially constructed chain on allocation\nfailure and letting the callers unwind it via their existing cleanup\npaths. Also fix ablk_perform() to preserve the hook pointers before\nchecking for failure, so partially built chains can be freed correctly."
