[PATCH v3 0/2] drm/tyr: safely write GpuInfo to userspace

[Deborah Brouwer <deborah.brouwer@collabora.com>]

This series makes zerocopy and zerocopy_derive available to the UAPI crate
so that zerocopy derive attributes can be added to generated UAPI
bindings. 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.
