8250_acpi.c #include's <acpi/acpi_bus.h> which requires config.h .

In the Linux kernel, it's more common to put such header dependencies 
for header files into the C files, but if the ACPI people agree a patch 
to add the #include <linux/config.h> to acpi_bus.h is the other possble 
correct solution for this issue.
