$(src) is the path to the directory where the source files are
located. $(obj) is the path to the directory where the output
is located.
They are both relative to the root of the kernel tree and thus
they are equal. We have $(src) and $(obj) only for documentation
purposes today.

In this case $(src) is correct as we want to point at where the
source files are located.
