Subject: [PATCH 2/3] PM: domains: Restructure some code in __genpd_dev_pm_attach()
Date: Thu,  2 Sep 2021 12:16:33 +0200	[thread overview]
Message-ID: <20210902101634.827187-3-ulf.hansson@linaro.org> (raw)
In-Reply-To: <20210902101634.827187-1-ulf.hansson@linaro.org>

To slightly improve readability of the code, but also to prepare for a
subsequent change on top, let's move the code that calls
of_get_required_opp_performance_state() into a new separate function.
