Hi all,

After the final merge today's linux-next build (arm64 allyesconfig)
failed like this, the same issue will be present in mainline:

error: field `device` is never read
  --> /tmp/next/build/drivers/gpu/drm/tyr/driver.rs:37:5
   |
36 | pub(crate) struct TyrDriver {
   |                   --------- field in this struct
37 |     device: ARef<TyrDevice>,
   |     ^^^^^^
   |
   = note: `-D dead-code` implied by `-D warnings`
   = help: to override `-D warnings` add `#[allow(dead_code)]`

error: fields `mali` and `sram` are never read
   --> /tmp/next/build/drivers/gpu/drm/tyr/driver.rs:196:5
    |
195 | struct Regulators {
    |        ---------- fields in this struct
196 |     mali: Regulator<regulator::Enabled>,
    |     ^^^^
197 |     sram: Regulator<regulator::Enabled>,
    |     ^^^^

error: aborting due to 2 previous errors

Caused by commit

   cf4fd52e32360 (rust: drm: Introduce the Tyr driver for Arm Mali GPUs)

I am continuing to mark the driver as BROKEN.
