From: Yu-Chun Lin <eleanor15x@xxxxxxxxx>
[ 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.
Fixes: eb1aac4c8744f75 ("HID: google: add support tablet mode switch for Whiskers")
