How to build samsung S22u kernel?

Question

First of all, I download the source code from the Samsung open source website(SM-S908U_NA_13_Opensource.zip).

Then download the cross-compilation tool chain and extract it to the corresponding folder

However, this error occurs when I run the compilation script：

or/cam_actuator_core.c:1636:9: error: redefinition of 'cam_actuator_i2c_read'
int32_t cam_actuator_i2c_read(struct cam_actuator_ctrl_t *a_ctrl, uint32_t addr,

I want to know how to compile the kernel code of Samsung successfully.
