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

From: Heinrich Schuchardt
Date: Sun Sep 10 2017 - 11:46:45 EST


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 '('.
