I did a review and pointed this out. No need for lengthy explanaitions.
Just remove it.

That's what Lennert said. And I agree. Many of the drivers just differ
in the hardware control function and the pyhsical address where the
device is located.

We have already platform support for NAND:

See include/linux/mtd/nand.h:

struct platform_nand_chip / struct platform_nand_ctrl

As far as I can tell, there is everything covered what you need for a
generic platform driver.

Again. Lennert is right and another post of your driver does not change
anything unless you listen to his and my advise.
