Akinobu Mita db6a3d03e2 dmaengine: xilinx: avoid memory corruption for device_prep_dma_memcpy() ... The device_prep_dma_memcpy() callback for this driver allocates a new xilinx_dma_tx_descriptor whose TX segments list is initialized as empty, but then gets invalid TX segment pointer by list_last_entry() from the empty TX segments list and memory corruption happens by the attempt to update the next descriptor in invalid TX segment pointer. This removes unnecessary memory access for nonexistent tail TX segment which causes memory corruption.
