From fcdf445ff42f036d22178b49cf64e92d527c1330 Mon Sep 17 00:00:00 2001 From: Gen Zhang Date: Tue, 28 May 2019 10:18:51 +0800 Subject: clk-sunxi: fix a missing-check bug in sunxi_divs_clk_setup() In sunxi_divs_clk_setup(), 'derived_name' is allocated by kstrndup(). It returns NULL when fails. 'derived_name' should be checked.
