Both in nand_do_read_ops() and nand_do_write_ops() there is a boolean called use_bufpoi which is set to true in case of unaligned request or when there is a need for a DMA-able buffer. It basically means "use a bounce buffer". Depending on the value of use_bufpoi, the bufpoi variable is always used and will either point to the original buffer or to the nand_chip structure "internal data buffer" (this buffer is allocated with kmalloc() on purpose so that it will be DMA-compliant). In all cases bufpoi is used so the boolean name is misleading. Rename use_bufpoi to be use_bouce_buf to be more accurate.
