Subject: [PATCH v2 1/2] clk: qcom: rpmh: skip undefined clocks when registering
Date: Mon,  6 Jan 2020 15:48:42 +0530
Message-ID: <1578305923-29125-2-git-send-email-tdas@codeaurora.org> (raw)
In-Reply-To: <1578305923-29125-1-git-send-email-tdas@codeaurora.org>

When iterating over a platform's available clocks in clk_rpmh_probe(),
check for undefined (null) entries in the clocks array.  Not all
clock indexes necessarily have clocks defined.
