Hi all,

After merging the rust-pin-init tree, today's linux-next build (x86_64
allmodconfig) failed like this:

error[E0282]: type annotations needed
--> rust/kernel/configfs.rs:154:26

154 | subsystem <- pin_init::zeroed().chain(
| ^^^^^^^^^^^^^^^^ cannot infer type of the type parameter `T` declared on the function `zeroed`

help: consider specifying the generic argument

154 | subsystem <- pin_init::zeroed::<T>().chain(

error: aborting due to 2 previous errors

For more information about this error, try `rustc --explain E0282`.

Caused by commit

0bcaea04244b ("rust: pin-init: rename `zeroed` to `init_zeroed`")

I have used the rust-pin-init tree from next-20250606 for today.
