[MTD] [NAND] nand_base.c: fix type of eccpos pointer
The nand_base.c driver implicitly casts the uint32_t eccpos array to 'int *', which is not only not guaranteed to be the same sign as the source, but is not guaranteed to be the same size. Fix by changing nand_base.c to use uint32_t referencing the eccpos fields. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: David Woodhouse <dwmw2@infradead.org>
