rust example register called twice. why? #127
Description
It's not issue, but a question.
https://github.com/Rust-for-Linux/linux/blob/rust/drivers/char/rust_example.rs#L140
let mut chrdev_reg =
chrdev::Registration::new_pinned(cstr!("rust_chrdev"), 0, &THIS_MODULE)?;
chrdev_reg.as_mut().register::<RustFile>()?;
chrdev_reg.as_mut().register::<RustFile>()?;
Why is register called twice?
Thank you

Because the goal is to demo what it looks like to register multiple chardevs on the same major number. We're being lazy and just using the same file type.
Would a comment explaining this help?
fixes #127 -- added a comment to clarify an example
