Subject: [PATCH v2 06/11] cpufreq: scmi: Avoid one OF parsing in scmi_get_sharing_cpus()
Date: Thu, 13 Jul 2023 16:17:33 +0200 [thread overview]
Message-ID: <20230713141738.23970-7-ulf.hansson@linaro.org> (raw)
In-Reply-To: <20230713141738.23970-1-ulf.hansson@linaro.org>
The domain-id for the cpu_dev has already been parsed at the point when
scmi_get_sharing_cpus() is getting called. Let's pass it as an in-parameter
to avoid the unnecessary OF parsing.
