From 63fb9623427fbb44e3782233b6e4714057b76ff2 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Fri, 21 Feb 2020 01:46:18 +0100 Subject: ACPI: PM: s2idle: Check fixed wakeup events in acpi_s2idle_wake() Commit fdde0ff8590b ("ACPI: PM: s2idle: Prevent spurious SCIs from waking up the system") overlooked the fact that fixed events can wake up the system too and broke RTC wakeup from suspend-to-idle as a result. Fix this issue by checking the fixed events in acpi_s2idle_wake() in addition to checking wakeup GPEs and break out of the suspend-to-idle loop if the status bits of any enabled fixed events are set then.
