[PATCH 5.13 076/113] opp: remove WARN when no valid OPPs remain

From: Greg Kroah-Hartman
Date: Wed Sep 01 2021 - 08:51:38 EST


From: Michał Mirosław <mirq-linux@xxxxxxxxxxxx>

[ 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.
