It seems like what was intended is to test if the dma_map of the
previous line failed but the wrong dma address was passed.

Applied to nand/next, thanks!
[1/1] mtd: rawnand: atmel: Fix dma_mapping_error() address
commit: 9e2e2576bc49c3bc352d402963f7ba8774c3d95f
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,
Miquèl
