[PATCH v4 0/2] drm/tyr: safely write GpuInfo to userspace

[Deborah Brouwer]

This series makes zerocopy and zerocopy_derive available to both the UAPI
and bindings crates.

It derives the zerocopy traits specifically for struct
drm_panthor_gpu_info, allowing Tyr to safely copy this struct byte-for-
byte into userspace memory.
