Subject: [PATCH AUTOSEL 4.4 34/43] wlcore: Add missing PM call for wlcore_cmd_wait_for_event_or_timeout()
Date: Mon, 17 Sep 2018 03:05:10 +0000	[thread overview]
Message-ID: <20180917030445.484-34-alexander.levin@microsoft.com> (raw)
In-Reply-To: <20180917030445.484-1-alexander.levin@microsoft.com>

From: Tony Lindgren <tony@atomide.com>

[ Upstream commit 4ec7cece87b3ed21ffcd407c62fb2f151a366bc1 ]

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.
