Kernel source of updated version

After updated to latest kernel 4.4.143-57-rockchip-g4b8d0571d76e from 4.4.143+, my Rockpi S does not work on Bluetooth due to lack of modules.

How do I build kernel modules of 4.4.143-57-rockchip-g4b8d0571d76e?
Probably I think I need new kernel source.

I rebuilt the kernel modules as revision of ‘4.4.143-57-rockchip-g4b8d0571d76e’. For the time being, it’s working. Please let me know if someone knows easy way.
