Subject: [PATCH v3 01/12] opp: Fix adding OPP entries in a wrong order if rate is unavailable
Date: Mon, 18 Jan 2021 03:55:13 +0300	[thread overview]
Message-ID: <20210118005524.27787-2-digetx@gmail.com> (raw)
In-Reply-To: <20210118005524.27787-1-digetx@gmail.com>

Fix adding OPP entries in a wrong (opposite) order if OPP rate is
unavailable. The OPP comparison was erroneously skipped, thus OPPs
were left unsorted.
