Subject: PNP: fix restoring devices after hibernation
From: Dmitry Torokhov <dmitry.torokhov@xxxxxxxxx>
commit 8a37ea50e7acf8db6821ba094ca41384e7d8c70c upstream.
On returning from hibernation 'restore' callback is called,
not 'resume'. Fix it.
Fixes: eaf140b60ec9 (PNP: convert PNP driver bus legacy pm_ops to dev_pm_ops)
