Subject: [PATCH] clk: rockchip: Fix memory leak in rockchip_clk_register_pll()
Date: Wed, 23 Nov 2022 11:22:37 +0800	[thread overview]
Message-ID: <20221123032237.64567-1-xiujianfeng@huawei.com> (raw)

If clk_register() fails, @pll->rate_table may have allocated memory by
kmemdup(), so it needs to be freed, otherwise will cause memory leak
issue, this patch fixes it.

Fixes: 90c590254051 ("clk: rockchip: add clock type for pll clocks and pll used on rk3066")
