Description

In the Linux kernel, the following vulnerability has been resolved:

ASoC: hdac_hda: Fix hlink refcount leak on component registration failure

hdac_hda_dev_probe() gets the HDA link with snd_hdac_ext_bus_link_get() before registering the ASoC component. If component registration fails, the function returns without dropping the link reference.

Always call snd_hdac_ext_bus_link_put() after the registration attempt so the reference taken during probe is balanced on both success and failure.
