I'm sorry, actually not a char array - I forgot we don't print just the letter,
but string (letter with a description).
You could accumulate string with strcat and print it at the end.
But maybe just use tst_res(TINFO, ...) to print the flag in the loop
and in the end tst_brk(TBROK, "Kernel is already tainted").

Kind regards,
Petr
