commit c0ad3645c9873a4680e9fefc89c9fea63094d93f Author: Nico Huber nico.h@gmx.de Date: Sun Dec 11 02:04:44 2016 +0100
sio/ite/it8783ef: Return (0) in ACPI _PSC methods
Current ACPI code for UARTs uses the PNP_DEFAULT_PSC macro for _PSC (current power state) methods. Override it to `Return (0)` (i.e. cur- rent state is D0) as the IT8783E/F doesn't have power management.
