How to update coolpi-4b npu driver in ubuntu?

traceback

I'm going to try rknn-llm, which need at least v0.9.6 driver version. The version in official ubuntu 22.04 is:

cat /sys/kernel/debug/rknpu/version
RKNPU driver: v0.8.2

I have tried built the rknpu v0.9.6 from rknn-llm repository,but it terminates with error

drivers/rknpu/rknpu_gem.c: In function 'rknpu_gem_mmap_buffer':
drivers/rknpu/rknpu_gem.c:988:9: error: implicit declaration of function 'vm_flags_clear' [-Werror=implicit-function-declaration]
  988 |         vm_flags_clear(vma, VM_PFNMAP);
      |         ^~~~~~~~~~~~~~
cc1: all warnings being treated as errors

Above outputs are raisen when I compile rknpu 0.9.6 under coolpi-kernel 5.10.110
Are there any way to solve the error or update the npu driver?

Thanks in advance!
