Error compiling kernel

[windskyxb]

I had a problem compiling the 5.10.160 kernel for Orange Pi 5 Plus.
I replaced the files in drivers/rknpu with those in rknpu_driver_0.9.6_20240322.tar.bz2 and added two functions to include/linux/mm.h, but still encountered a compilation error:
drivers/rknpu/rknpu_devfreq.c: In function 'rknpu_devfreq_init':
drivers/rknpu/rknpu_devfreq.c:732:9: error: implicit declaration of function 'rockchip_uninit_opp_table'; did you mean 'rockchip_init_opp_table'? [-Werror=implicit-function-declaration]
732 | rockchip_uninit_opp_table(dev, &rknpu_dev->opp_info);
