Subject: [PATCH] rtc: sun6i: Fix memleak in sun6i_rtc_clk_init
Date: Sun, 23 Aug 2020 15:58:15 +0800 [thread overview]
Message-ID: <20200823075815.23457-1-dinghao.liu@zju.edu.cn> (raw)
When clk_hw_register_fixed_rate_with_accuracy() fails,
clk_data should be freed. It's the same for the subsequent
error paths.
