mtd: nand: atmel: Use uintptr_t casts instead of unsigned int

Boris Brezillon · ambarus · commit 8ab284758c1d · 2018-08-22T19:13:28.000+03:00
When casting a pointer to an unsigned int, uintptr_t should be used to
cope with the pointer size differences between 32-bit and 64-bit
architectures.

This is needed if we want to allow compilation of this driver when
COMPILE_TEST=y.
