Subject: linux-next: build failure after merge of the rust tree

Hi all,

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

error[E0308]: mismatched types
   --> drivers/gpu/drm/drm_panic_qr.rs:961:60

error: aborting due to 1 previous error

For more information about this error, try `rustc --explain E0308`.

Caused by commit

  e721cd7570b2 ("rust: map `long` to `isize` and `char` to `u8`")

I have used the rust tree from next-20241213 for today.
