Linux kernel source tree
fc55584e00
When `CONFIG_AUXILIARY_BUS` is disabled, `parent()` is still dead code:
error: method `parent` is never used
--> rust/kernel/device.rs:71:19

64 | impl<Ctx: DeviceContext> Device<Ctx> {
| ------------------------------------ method in this implementation
...
71 | pub(crate) fn parent(&self) -> Option<&Self> {
| ^^^^^^
|
= note: `-D dead-code` implied by `-D warnings`
= help: to override `-D warnings` add `#[allow(dead_code)]`
Thus reintroduce the `expect`, but now as a conditional one. Do so as
`dead_code` since that is narrower.
An `allow` would also be possible, but Danilo wants to catch new users
in the future [1].

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
