From 65ab96f60621c4da8f1b4087a57b788bc4d8f27b Mon Sep 17 00:00:00 2001 From: Andreas Fleig Date: Sun, 27 Jan 2013 14:17:55 +0000 Subject: ACPI / PM: Fix /proc/acpi/wakeup for devices w/o bus or parent Fix /proc/acpi/wakeup for devices without bus or parent This patch fixes printing the wakeup status for devices without a bus or parent, such as laptop lid switches and sleep buttons. These devices have an empty physical_node_list, because acpi_bind_one is never run for them. [rjw: White space and coding style.] Signed-off-by: Andreas Fleig Signed-off-by: Rafael J.
