[PATCH v2 1/2] clk: qcom: rpmh: skip undefined clocks when registering

From: Taniya Das
Date: Mon Jan 06 2020 - 05:19:45 EST


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.
