From b55226f8553d255f5002c751c7c6ba9291f34bf2 Mon Sep 17 00:00:00 2001 From: Xiu Jianfeng Date: Tue, 22 Nov 2022 23:23:53 +0800 Subject: [PATCH] clk: visconti: Fix memory leak in visconti_register_pll() @pll->rate_table has allocated memory by kmemdup(), if clk_hw_register() fails, it should be freed, otherwise it will cause memory leak issue, this patch fixes it.
