From 4283afde4f8dcfb9cc6bd08d1746f5c24838e485 Mon Sep 17 00:00:00 2001 From: Yu-Chun Lin Date: Tue, 18 Feb 2025 00:50:13 +0800 Subject: [PATCH] HID: google: fix unused variable warning under !CONFIG_ACPI [ Upstream commit 4bd0725c09f377ffaf22b834241f6c050742e4fc ] As reported by the kernel test robot, the following warning occurs: >> drivers/hid/hid-google-hammer.c:261:36: warning: 'cbas_ec_acpi_ids' defined but not used [-Wunused-const-variable=] 261 | static const struct acpi_device_id cbas_ec_acpi_ids[] = { | ^~~~~~~~~~~~~~~~ The 'cbas_ec_acpi_ids' array is only used when CONFIG_ACPI is enabled. Wrapping its definition and 'MODULE_DEVICE_TABLE' in '#ifdef CONFIG_ACPI' prevents a compiler warning when ACPI is disabled.
