I encountered an error message when compiling:
ERROR: module '/home/jack/openwrt/build_dir/target-aarch64_cortex-a53+neon_musl/linux-msm89xx_msm8916/linux-5.15.131/drivers/soc/qcom/mdt_loader.ko' is missing.
I entered the directory and saw mdt_loader.c. How to configure and compile .c to .ko?
enable the module in kernel config ?

I think I found it.
In target/linux//Makefile, the kernel version is set.
And set in target/linux//config-version
CONFIG_QCOM_SCM=y
I copied a copy of config-5.10 from 21.02 which compiles
Now compiled
Of course there are many configuration items
