From 4ec7cece87b3ed21ffcd407c62fb2f151a366bc1 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Tue, 19 Jun 2018 02:43:35 -0700 Subject: wlcore: Add missing PM call for wlcore_cmd_wait_for_event_or_timeout() Otherwise we can get: WARNING: CPU: 0 PID: 55 at drivers/net/wireless/ti/wlcore/io.h:84 I've only seen this few times with the runtime PM patches enabled so this one is probably not needed before that. This seems to work currently based on the current PM implementation timer. Let's apply this separately though in case others are hitting this issue.
