How to define file_operations for kernel ioctl call


I have a kernel function device_ioctl(). How do I define it in file_operations?

1. struct file_operations memory_fops = {
ioctl:device_ioctl
};
2. struct file_operations memory_fops = {
.ioctl=device_ioctl
};
3. struct file_operations memory_fops = {
device_ioctl
};
which one is the right one?

Thanks

the second one should work fine, but this is the wrong forum i guess for kernel programming related queries. And, please do a little Google search before you post a question.
