如何在编译Android内核时修复函数的隐式声明

Question

I have imported qcacld-3.0 driver from CAF which is default WLAN driver for my device. However, I am getting this error which I can't get how to fix. It seems perfectly declared to me. I am still a beginner at C, so might be missing something. Kindy, explain me how to fix this error and why that particular fix is chosen. Here is my kernel source .

Answer 1

通过在头文件中添加声明进行修复。
