From 29d99b966d60029a11d08b9b004cd84b21ce0d67 Mon Sep 17 00:00:00 2001 From: Shawn Nematbakhsh Date: Tue, 14 Feb 2017 20:58:02 +0100 Subject: cros_ec: Don't signal wake event for non-wake host events The subset of wake-enabled host events is defined by the EC, but the EC may still send non-wake host events if we're in the process of suspending. Get the mask of wake-enabled host events from the EC and filter out non-wake events to prevent spurious aborted suspend attempts.
