From b7a52d3cd6d241c4c88028deea19a5de04c34a95 Mon Sep 17 00:00:00 2001 From: Nico Huber Date: Sun, 11 Dec 2016 02:04:44 +0100 Subject: 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.
