    Subject[PATCH trivial next 9/9] gadget: Use vsprintf extention %pf with builtin_return_address
    Emit the function name not the address when possible.

    builtin_return_address() gives an address. When building
    a kernel with CONFIG_KALLSYMS, emit the actual function
    name not the address.
