From 0e213813df02da048ffd22a2c4fac041768ca327 Mon Sep 17 00:00:00 2001 From: Yang Yingliang Date: Thu, 20 Oct 2022 18:59:37 +0800 Subject: ASoC: Intel: Skylake: fix possible memory leak in skl_codec_device_init() If snd_hdac_device_register() fails, 'codec' and name allocated in dev_set_name() called in snd_hdac_device_init() are leaked. Fix this by calling put_device(), so they can be freed in snd_hda_codec_dev_release() and kobject_cleanup().
