[ Upstream commit 6933c1067fe6df8ddb34dd68bdb2aa172cbd08c8 ]
Several pr_info! calls in rust/kernel/init.rs (both in code examples and macro documentation) were missing a newline, causing logs to run together. This commit updates these calls to include a trailing newline, improving readability and consistency with the C side.
Fixes: 6841d45a3030 ("rust: init: add `stack_pin_init!` macro") Fixes: 7f8977a7fe6d ("rust: init: add `{pin_}chain` functions to `{Pin}Init<T, E>`") Fixes: d0fdc3961270 ("rust: init: add `PinnedDrop` trait and macros") Fixes: 4af84c6a85c6 ("rust: init: update expanded macro explanation") Reported-by: Miguel Ojeda ojeda@kernel.org Link: https://github.com/Rust-for-Linux/linux/issues/1139 Signed-off-by: Alban Kurti kurti@invicto.ai Link: https://lore.kernel.org/r/20250206-printing_fix-v3-3-a85273b501ae@invicto.ai [ Replaced Closes with Link since it fixes part of the issue.
