If CONFIG_ACPI is not set,
gcc warns about unused variable:
drivers/i2c/busses/i2c-mlxbf.c:2206:35: error: ‘mlxbf_i2c_chip’ defined but not used [-Werror=unused-variable]
static struct mlxbf_i2c_chip_info mlxbf_i2c_chip[] = {
^~~~~~~~~~~~~~
cc1: all warnings being treated as errors
Mark these variables as __maybe_unused to fix this.
