Subject: [PATCH AUTOSEL 5.13 04/26] opp: remove WARN when no valid OPPs remain
Date: Mon, 23 Aug 2021 20:53:34 -0400	[thread overview]
Message-ID: <20210824005356.630888-4-sashal@kernel.org> (raw)
In-Reply-To: <20210824005356.630888-1-sashal@kernel.org>

From: Michał Mirosław <mirq-linux@rere.qmqm.pl>

[ Upstream commit 335ffab3ef864539e814b9a2903b0ae420c1c067 ]

This WARN can be triggered per-core and the stack trace is not useful.
Replace it with plain dev_err(). Fix a comment while at it.
