From a6e3b2aedf8af18693c488bcf65c53bef7d46941 Mon Sep 17 00:00:00 2001 From: Dragos Tarcatu Date: Fri, 7 Feb 2020 20:53:24 +0200 Subject: [PATCH] ASoC: topology: Fix memleak in soc_tplg_link_elems_load() commit 2b2d5c4db732c027a14987cfccf767dac1b45170 upstream. If soc_tplg_link_config() fails, _link needs to be freed in case of topology ABI version mismatch. However the current code is returning directly and ends up leaking memory in this case. This patch fixes that.
