Subject: [PATCH v4 10/15] clk: qcom: Use ARRAY_SIZE in gpucc-sc7180 for parent clocks
Date: Mon,  3 Feb 2020 10:31:43 -0800
Message-ID: <20200203103049.v4.10.I3bf44e33f4dc7ecca10a50dbccb7dc082894fa59@changeid> (raw)
In-Reply-To: <20200203183149.73842-1-dianders@chromium.org>

It's nicer to use ARRAY_SIZE instead of hardcoding.  Had we always
been doing this it would have prevented a previous bug.  See commit
74c31ff9c84a ("clk: qcom: gpu_cc_gmu_clk_src has 5 parents, not 6").
