Subject: [PATCH 1/2] serial: 8250_platform: remove ACPI_PTR() annotation

From: Arnd Bergmann <arnd@...db.de>

The acpi_platform_serial_table[] array is defined globally without
an #ifdef check for CONFIG_ACPI, so ACPI_PTR() makes no sense
here:

drivers/tty/serial/8250/8250_platform.c:271:36: error: 'acpi_platform_serial_table' defined but not used [-Werror=unused-const-variable=]
  271 | static const struct acpi_device_id acpi_platform_serial_table[] = {

Fixes: d9e5a0ce2f16 ("serial: 8250_platform: Enable generic 16550A platform devices")
