The function sunxi_nfc_hw_ecc_write_chunk() calls the
sunxi_nfc_hw_ecc_write_chunk(), but does not call the configuration
function sunxi_nfc_randomizer_config(). Consequently, the randomization
might not conduct correctly, which will affect the lifespan of NAND flash.
A proper implementation can be found in sunxi_nfc_hw_ecc_write_page_dma().
Add the sunxi_nfc_randomizer_config() to config randomizer.
Fixes: 4be4e03efc7f ("mtd: nand: sunxi: add randomizer support")

Please next time send all these "identical" changes in a single patch.

Applied to nand/next, thanks!
[1/1] mtd: nand: sunxi: Add randomizer configuration in sunxi_nfc_hw_ecc_write_chunk
(no commit info)
Patche(s) should be available on mtd/linux.git and will be
part of the next PR (provided that no robot complains by then).
Kind regards,
