commit e9441675edc1bb8dbfadacf68aafacca60d65a25 upstream.
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().
Fixes: 829c67319806 ("ASoC: SOF: Intel: Introduce HDA codec init and exit routines")
Fixes: dfe66a18780d ("ALSA: hdac_ext: add extended HDA bus")
