I was playing with some code that sometimes got a string where a %n
match should have been done where the input string ended, for example
like this:
sscanf("abc123", "abc%d%n", &a, &n); /* doesn't work */
sscanf("abc123a", "abc%d%n", &a, &n); /* works */
However, the scanf function in the kernel doesn't convert the %n in that
case because it has already matched the complete input after %d and just
completely stops matching then. This patch fixes that.
