Subject: [PATCH] ACPI: PM: Print debug messages when enabling GPEs for wakeup
Date: Wed, 03 Apr 2019 23:58:01 +0200 [thread overview]
Message-ID: <3571352.AeSAkbixj6@aspire.rjw.lan> (raw)
From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
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.
