From a75b9b333aeb045fdb7f610b85f8b5305a2d706d Mon Sep 17 00:00:00 2001 From: Luca Coelho Date: Tue, 21 Aug 2018 07:24:18 +0300 Subject: [PATCH] iwlwifi: mvm: protect D0i3 code behind CONFIG_PM Runtime PM can only be used if CONFIG_PM is set. Move all the d0i3 code (which is essentially runtime PM) behind the CONFIG_PM flag. This prevents undefined usage of some functions when CONFIG_PM is not defined.
