Description

I got this error:

error: the feature `asm_const` has been stable since 1.82.0 and no longer requires an attribute to enable
 --> src/main.rs:109:12

109 | #![feature(asm_const)]
 | ^^^^^^^^^

 = note: `-D stable-features` implied by `-D warnings`
 = help: to override `-D warnings` add `#[allow(stable_features)]`

so I removed the line and created this PR. I tested it in QEMU and it worked. Real HW raspberry Pi is not applicable since it's just tutorial 2.

Pre-commit steps

• Tested on QEMU and real HW Rasperry Pi.
  • Not needed if it is just a README change or similar.
• Ran ./contributor_setup.sh followed by ./devtool ready_for_publish
  • You'll need Ruby with Bundler and NPM installed locally.
  • If no Rust-related files were changed, ./devtool ready_for_publish_no_rust can be used instead (faster).
  • This step is optional, but much appreciated if done.
