Subject: [PATCH] serial: 8250_platform: Fix unused acpi_platform_serial_table warning
The LKP reports below warning.
>> drivers/tty/serial/8250/8250_platform.c:271:36: warning: 'acpi_platform_serial_table' defined but not used [-Wunused-const-variable=]
271 | static const struct acpi_device_id acpi_platform_serial_table[] = {
| ^~~~~~~~~~~~~~~~~~~~~~~~~~
This is because some architectures don't define either ACPI or
MODULE/MODULE_DEVICE_TABLE. So, keep acpi_platform_serial_table under
CONFIG_ACPI to fix the warning on such architectures.
Reported-by: kernel test robot <lkp@...el.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202407310047.PIoWlrZZ-lkp@intel.com/
Fixes: d9e5a0ce2f16 ("serial: 8250_platform: Enable generic 16550A platform devices")
