Subject: [cip-dev] [PATCH 4.4.y-cip v3 09/14] PM / OPP: Set cpu_dev->id in cpumask first
Date: Tue, 9 Jun 2020 12:09:21 +0800 [thread overview]
Message-ID: <20200609040926.8910-10-wens@csie.org> (raw)
In-Reply-To: <20200609040926.8910-1-wens@csie.org>
[-- Attachment #1: Type: text/plain, Size: 1435 bytes --]
From: Pi-Cheng Chen <pi-cheng.chen@linaro.org>
commit d9de19b1cc013433ad293365b5b3902ec73dfd60 upstream.
Set cpu_dev->id in cpumask first when setting up cpumask for CPUs that
share the same OPP table. This might be helpful when handling cpumask
without the original CPU bitfield set.
