From 10f91c73cc41ceead210a905dbd196398e99c7d2 Mon Sep 17 00:00:00 2001 From: Vitaly Kuznetsov Date: Thu, 15 Nov 2018 11:05:10 -0800 Subject: [PATCH] Input: hyper-v - fix wakeup from suspend-to-idle It makes little sense but still possible to put Hyper-V guests into suspend-to-idle state. To wake them up two wakeup sources were registered in the past: hyperv-keyboard and hid-hyperv. However, since commit eed4d47efe95 ("ACPI / sleep: Ignore spurious SCI wakeups from suspend-to-idle") pm_wakeup_event() from these devices is ignored. Switch to pm_wakeup_hard_event() API as these devices are actually the only possible way to wakeup Hyper-V guests.
