Subject: [PATCH v2 4/5] clk: qcom: use common code for qcom_cc_probe_by_index
Date: Wed, 28 Jul 2021 17:24:44 +0300	[thread overview]
Message-ID: <20210728142445.774158-5-dmitry.baryshkov@linaro.org> (raw)
In-Reply-To: <20210728142445.774158-1-dmitry.baryshkov@linaro.org>

Rewrite qcom_cc_map and qcom_cc_probe_by_index to use (new)
qcom_cc_map_by_index, removing code duplication and opening a way to
have more common code in qcom_cc_map*.
