From: Miaoqian Lin <linmq006@gmail.com> stable inclusion from stable-v5.10.110 commit 1f24716e38220fc9e52e208d20591d2bc9b7f020 bugzilla: https://gitee.com/openeuler/kernel/issues/I574AL Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ Upstream commit 9531a631379169d57756b2411178c6238655df88 ] The device_node pointer is returned by of_parse_phandle() with refcount incremented. We should use of_node_put() on it when done. This is similar to commit 64b92de9603f ("ASoC: wcd9335: fix a leaked reference by adding missing of_node_put") Fixes: a61f3b4f476e ("ASoC: wcd934x: add support to wcd9340/wcd9341 codec") Signed-off-by: Miaoqian Lin <linmq006@gmail.com> Link: https://lore.kernel.org/r/20220316083631.14103-1-linmq006@gmail.com Signed-off-by: Mark Brown <broonie@kernel.org> Signed-off-by: Sasha Levin <sashal@kernel.org> Signed-off-by: Yu Liao <liaoyu15@huawei.com> Reviewed-by: Wei Li <liwei391@huawei.com> Signed-off-by: Zheng Zengkai <zhengzengkai@huawei.com> --- sound/soc/codecs/wcd934x.c | 1 + 1 file changed, 1 insertion(+) diff --git a/sound/soc/codecs/wcd934x.c b/sound/soc/codecs/wcd934x.c index f07dea0bc27e..8540ac230d0e 100644 --- a/sound/soc/codecs/wcd934x.c +++ b/sound/soc/codecs/wcd934x.c @@ -5047,6 +5047,7 @@ static int wcd934x_codec_parse_data(struct wcd934x_codec *wcd) } wcd->sidev = of_slim_get_device(wcd->sdev->ctrl, ifc_dev_np); + of_node_put(ifc_dev_np); if (!wcd->sidev) { dev_err(dev, "Unable to get SLIM Interface device\n"); return -EINVAL; -- 2.20.1
