do_div is the wrong way to divide a sector_t, as it is less efficient when sector_t is 32-bit wide. With the upcoming do_div optimizations, the kernel starts warning about this: drivers/memstick/core/ms_block.c: In function 'msb_io_work': include/asm-generic/div64.h:207:28: warning: comparison of distinct pointer types lacks a cast This changes the code to use sector_div instead, which always produces optimal code.
