On some 32-bit platforms (at least on parisc), the compiler generates a call to __divdi3() from the u32 by 3 division in rkcanfd_timestamp_init(), which results in the following linker error: | ERROR: modpost: "__divdi3" [drivers/net/can/rockchip/rockchip_canfd.ko] undefined! As this code doesn't run in the hot path, a 64 bit by 32 bit division is OK, even on 32 bit platforms. Use an explicit call to div_u64() to fix linking.
