These `srctree/` links pointed inside `linux/`, but they are directly
under `drm/`.

Thus fix them.

This cleans a future warning that will check our `srctree/` links.

drm: rust: rename as_ref() to from_raw() for drm constructors 2025-07-11T14:30:30+00:00 Alice Ryhl aliceryhl@google.com 2025-07-11T08:04:38+00:00 917b10d90990fd2138b5dbc2d22cfa428c070ade The prefix as_* should not be used for a constructor.

A DRM File is the DRM counterpart to a kernel file structure,
representing an open DRM file descriptor.

Add a Rust abstraction to allow drivers to implement their own File types
that implement the DriverFile trait.
