No longer able to cargo update to latest revision

[laniakea64]

I have a local Rust CLI tool that uses system76-firmware as a library. It used to be possible to update its system76-firmware dependency by running cargo update, however in the last couple days this is no longer working:

$ cargo --version
cargo 1.84.0 (66221abde 2024-11-19)
$ cargo update
    Updating crates.io index
    Updating git repository `https://github.com/pop-os/system76-firmware`

    ... which satisfies git dependency `system76-firmware-daemon` of package `...`

Caused by:

Caused by:
  Unable to update https://github.com/system76/ecflash.git?branch=stable

Caused by:
  failed to find branch `stable`

Caused by:
  cannot locate remote-tracking branch 'origin/stable'; class=Reference (4); code=NotFound (-3)

In case it might be relevant for reproducing the error, the environment where this update is being performed is starting with an empty CARGO_HOME directory.

Thanks for your review.

Looks like stable was deleted at some point.

stable used the package name ecflash, but the package name has been changed to system76_ecflash.

Use of nightly features (asm, alloc) was replaced by stable features, but needs to be checked that it still works with current HEAD.
