From: Linus Walleij <linus.walleij@xxxxxxxxxx> The ACPI states are used by the serial core by way of magic numbers in the code, it's pretty confusing, so we need to reference the definitions from the actual ACPI includes. This breaks out the state definitons. The entire <acpi/actypes.h> include can not be used since that file will not compile for a machine that is not using ACPI due to things like this: #ifndef ACPI_MACHINE_WIDTH #error ACPI_MACHINE_WIDTH not defined #endif So just break it out, include it back into the original file and be done with it. After this the serial core can piggyback the actual state definitions from the ACPI subsystem.
