[PATCH 6.18.y 0/5] Four Rust Devres fixes

[Alice Ryhl <aliceryhl@google.com>]

These fixes were not picked up because of some conflicts and/or build
failures, but they are important to avoid deadlocks and races. Please
pick them up for 6.18, thanks!

Unfortunately, it turns out that backporting these fixes introduces a
bug in the irq abstraction due to the fact that it makes Devres
allocate. This bug is not present in mainline because irq no longer uses
Devres at all upstream. I included a fix for this as well.
