Subject: [PATCH v2 2/5] PM: clk: add devm_pm_clk_create helper
Date: Wed, 28 Jul 2021 17:24:42 +0300 [thread overview]
Message-ID: <20210728142445.774158-3-dmitry.baryshkov@linaro.org> (raw)
In-Reply-To: <20210728142445.774158-1-dmitry.baryshkov@linaro.org>
Add devm_pm_clk_create helper, devres-enabled version of the
pm_clk_create(), which will call pm_clk_destroy at the correct time.
