Subject: [PATCH -next] cpufreq: qcom-hw: Fix memory leak in qcom_cpufreq_hw_driver_probe()
Date: Tue, 22 Nov 2022 20:46:27 +0800	[thread overview]
Message-ID: <20221122124627.174403-1-xiujianfeng@huawei.com> (raw)

If devm_clk_hw_register() fails, clk_init.name should be freed before
return error, otherwise will cause memory leak issue, fix it.

Fixes: 84063a1cbe9e ("cpufreq: qcom-hw: Add CPU clock provider support")
