6.6-stable review patch. If anyone has any objections, please let me know. ------------------ From: Haoxiang Li [ Upstream commit 6ad4892c4f5cb437a928a02f5b7d37d496aa9268 ] 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.
