[PATCH v2 1/1] scripts/checkpatch.pl: avoid false warning missing break

[Heinrich Schuchardt]

void foo(int a)
        switch (a) {
        case 'h':
                fun1();
                exit(1);
        default:
}

creates a warning
Possible switch case/default not preceded by break
or fallthrough comment

exit( should be treated like return.

v2:
        Allow whitespace between 'exit' and '('.
