Subject[PATCH 1/2] kconfig: clean up nested if-conditionals in check_conf()
Date
Unify the outer two if-conditionals into one. This decreases the
indent level by one.

Also, change the if-else blocks:

if (input_mode == listnewconfig) {
...
} else if (input_mode == helpnewconfig) {
...
} else {
...
}

into the switch statement.
