when parsing /proc/interrupts and if a chip name start with numbers, current procedure would consider those numbers as interrupt count thus lead to miscount. Failed parsing would trigger new parsing and cause dead loop which can't be stopped by SIGINT and SIGTERM. So fix this by adding signal checks in loop. Signed-off-by: qinyu <qinyu32@huawei.com>
