How to convert function pointer to function name

[J.H.Kim]

Hi, everyone

How can I convert function pointer to function symbol to print out the 
name of the function?

For example, in console_init(), I'd like to print out the function name 
of (*call)() using printk().

        call = __con_initcall_start;

        while (call < __con_initcall_end) {
                (*call)();
                call++;
        }

Is it only way to find out the function symbol
that compare the address of call with those in System.map?

If there is other methods to do it, please let me know them.

Thanks in advance.

Regards,
J.H.Kim
