Subject: [PATCH 4.19 20/33] opp: remove WARN when no valid OPPs remain
Date: Wed,  1 Sep 2021 14:28:09 +0200	[thread overview]
Message-ID: <20210901122251.460053963@linuxfoundation.org> (raw)
In-Reply-To: <20210901122250.752620302@linuxfoundation.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.
