From 21dbc2fc3c2febe0e6ac3760f4c8a63c2aeedd06 Mon Sep 17 00:00:00 2001 From: Martin Roth Date: Mon, 23 Nov 2015 12:23:19 -0700 Subject: ec/lenovo/h8: Fix IASL warnings If any path in a method returns a value, IASL expects that all paths within that method will return a value. Presumably the MKHP method wouldn't get called unless there were a pending event, but if no event is found, return a zero. Fixes IASL warning: dsdt.aml 1785: Method (MHKP, 0, NotSerialized) Warning 3115 - ^ Not all control paths return a value (MHKP) This was the only IASL warning in most lenovo mainboards.
