From 0ae3aeefabbeef26294e7a349b51f1c761d46c9f Mon Sep 17 00:00:00 2001 From: Ulf Hansson Date: Fri, 8 Apr 2016 13:10:23 +0200 Subject: [PATCH] PM / Runtime: Fix error path in pm_runtime_force_resume() As pm_runtime_set_active() may fail because the device's parent isn't active, we can end up executing the ->runtime_resume() callback for the device when it isn't allowed. Fix this by invoking pm_runtime_set_active() before running the callback and let's also deal with the error code.
