From 05a2b0011c4b6cbbc9b577f6abebe4e9333b0cf6 Mon Sep 17 00:00:00 2001 From: Lukas Fischer kernel@o1oo11oo.de Date: Fri, 4 Apr 2025 14:51:51 +0200 Subject: [PATCH] scripts: generate_rust_analyzer: Add ffi crate

Commit d072acda4862 ("rust: use custom FFI integer types") did not update rust-analyzer to include the new crate.

To enable rust-analyzer support for these custom ffi types, add the `ffi` crate as a dependency to the `bindings`, `uapi` and `kernel` crates, which all directly depend on it.
