TOMOYO: Return appropriate value to poll(). "struct file_operations"->poll() expects "unsigned int" return value. All files in /sys/kernel/security/tomoyo/ directory other than /sys/kernel/security/tomoyo/query and /sys/kernel/security/tomoyo/audit should return POLLIN | POLLRDNORM | POLLOUT | POLLWRNORM rather than -ENOSYS. Also, /sys/kernel/security/tomoyo/query and /sys/kernel/security/tomoyo/audit should return POLLOUT | POLLWRNORM rather than 0 when there is no data to read.
