From 9d68320b2bca876278856fdc1e8684a7494dd069 Mon Sep 17 00:00:00 2001 From: Huisong Li Date: Fri, 5 Sep 2025 16:18:58 +0800 Subject: [PATCH] ACPI: processor: idle: Fix function defined but not used warning If CONFIG_ACPI_PROCESSOR_IDLE=n, acpi_processor_register_idle_driver() and acpi_processor_unregister_idle_driver() are never used and the empty stubs of them are not needed. Moreover, they cause the compiler to complain [1], so remove them.
