From fbc9418f099d457b91bf14aef8c4bfc498bb2437 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Wed, 3 Apr 2019 23:58:01 +0200 Subject: ACPI: PM: Print debug messages when enabling GPEs for wakeup In sufficiently complicated GPE configurations it is hard to determine which GPE could be the source of system wakeup from a sleep state, so make __acpi_device_wakeup_enable() print that information to the kernel log if debugging is enabled.
