[PATCH 1/3] mtd: spinand: winbond: Fix W35N number of planes/LUN

[Miquel Raynal]

There's been a mistake when extracting the geometry of the W35N02 and
W35N04 chips from the datasheet. There is a single plane, however there
are respectively 2 and 4 LUNs. They are actually referred in the
datasheet as dies (equivalent of target), but as there is no die select
operation and the chips only feature a single configuration register for
the entire chip (instead of one per die), we can reasonably assume we
are talking about LUNs and not dies.
