From 62006c1702b3b1be0c0726949e0ee0ea2326be9c Mon Sep 17 00:00:00 2001 From: Ulf Hansson Date: Mon, 17 Oct 2016 20:16:58 +0200 Subject: [PATCH] PM / Runtime: Remove the exported function pm_children_suspended() The exported function pm_children_suspended() has only one caller, which is the runtime PM internal function, rpm_check_suspend_allowed(). Let's clean-up this code, by removing pm_children_suspended() altogether and instead do the one-liner check directly in rpm_check_suspend_allowed().
