Recent GCC versions warn if the format string is not a literal
because the compiler cannot check the argument validity at compile
time.
Commit 192bc6948b02 ("Fix GCC format-security errors and convert
sprintfs.") blindly replaced sprintf() with strcpy(), including
many cases where the format parameter is a string literal.
For the kconfig change:
sprintf(header, " ");
..., here the format parameter is a string literal " ", so it is
definitely equivalent to:
strcpy(header, " ");
Of course, if the 'header' did not have enough length for containing
" ", it would be a security problem, but another problem. (in this
case, the 'header' is 4 byte length buffer, so it is not a problem at
all.)
The kconfig code is kept as synced with Linux as possible, but this
change made the code out-of-sync for nothing. Just reverting.
