From 2cf7bdec2db81730610edb2631252b39375024a0 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Pali=20Roh=C3=A1r?= Date: Sat, 12 Aug 2017 09:44:17 +0200 Subject: platform/x86: peaq-wmi: Evaluate wmi method with instance number 0x0 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit According to Hans de Goede, WMI interface of thh peaq-wmi module has 10 instances but corresponding ACPI WMBC method does not check Arg0 (instance number) at all. Therefore evaluate WMI method with first instance number (0x0) instead of second (0x1).
