Subject: [PATCH v2 7/7] clk: Zero init clk_init_data in helpers
Date: Sun, 18 Aug 2019 00:06:14 +0530
Message-ID: <20190817183614.8429-8-manivannan.sadhasivam@linaro.org> (raw)
In-Reply-To: <20190817183614.8429-1-manivannan.sadhasivam@linaro.org>

The clk_init_data struct needs to be initialized to zero for the new
parent_map implementation to work correctly. Otherwise, the member which
is available first will get processed.
