Building Rust Binder breaks with:

    error[E0061]: this method takes 1 argument but 2 arguments were supplied
       --> drivers/android/binder/node/wrapper.rs:86:50

    86  |                 _drop_outside_lock = owner_inner.push_work(&node.owner, node2);

    note: method defined here
       --> drivers/android/binder/process.rs:172:19
        |
    172 |     pub(crate) fn push_work(
        |                   ^^^^^^^^^
    173 |         &mut self,
    174 |         work: DLArc<dyn DeliverToRead>,
        |         ------------------------------

(and similarly in `drivers/android/binder/node.rs:740`).

It is due to upstream commit:

  dbb17c9ea756 ("rust_binder: move (e)poll wait queue to Process")

which added a `&Process` parameter to `push_work`.

7.12.y breaks similarly.
