Subject: [PATCH] ACPI: Use LIST_HEAD() to initialize on stack list head
Date: Tue, 19 May 2026 13:54:45 +0800 [thread overview]
Message-ID: <20260519055445.13122-1-jszhang@kernel.org> (raw)
Use LIST_HEAD to initialize on stack list head. No intentional
functional impact.
Change generated with below coccinelle script:
@@
identifier name;
@@
- struct list_head name;
+ LIST_HEAD(name);
... when != name
- INIT_LIST_HEAD(&name);
