From 69652f32c9ac71e2b0c8ed407e13ad905e00e947 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Fri, 13 Mar 2026 13:59:17 +0100 Subject: ACPI: event: Redefine acpi_notifier_call_chain() Notice that acpi_notifier_call_chain() only uses its device argument to retrieve the pnp.device_class and pnp.bus_id values from there, so it can be redefined to take pointers to those two strings as parameters istead of a struct acpi_device pointer. That allows all of its callers to pass a string literal as its first argument, so they won't need to initialize pnp.device_class in struct acpi_device objects operated by them any more, and its signature becomes more similar to acpi_bus_generate_netlink_event() then. Update the code as per the above. No intentional functional impact. Signed-off-by: Rafael J.
