From 41275eb5c7181febdfaa63c3a0ad9b7acdadcd52 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Mon, 15 Jul 2019 23:51:19 +0200 Subject: ACPI: PM: Set s2idle_wakeup earlier and clear it later The role of the s2idle_wakeup variable is to cause acpi_pm_wakeup_event() and acpi_pm_notify_handler() to increment pm_abort_suspend and trigger a wakeup from suspend-to-idle in case the ACPI SCI wakeup was canceled by acpi_s2idle_wake(). However, for this purpose it need not be set in acpi_s2idle_wake() and cleared in acpi_s2idle_sync(), respectively. In fact, it may be set as early as in acpi_s2idle_prepare() and cleared as late as in acpi_s2idle_restore(), so do that to allow subsequent changes to be simpler. This change is not expected to alter functionality. Signed-off-by: Rafael J.
