Does this improve performance or is this only for correctness?

Patch LGTM otherwise.

BTW, I also noticed that there is a do_div() call in spi_nor_write()
that also uses a u64 dividend and u32 divisor. I was wondering why it
uses do_div() and not div_u64() (I am not sure what the difference
between the two is) but I suppose it doesn't matter much since your
spring cleaning series will delete that code anyway.
