Subject: [PATCH v1 1/2] clk: qcom: rpmh: skip undefined clocks when registering
Date: Tue, 31 Dec 2019 16:30:47 +0530
Message-ID: <1577790048-18263-2-git-send-email-tdas@codeaurora.org> (raw)
In-Reply-To: <1577790048-18263-1-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. Also remove referencing
the clock name before valid hardware.
