If component registration fails,\nthe function returns without dropping the link reference.\n\nAlways call snd_hdac_ext_bus_link_put() after the registration attempt so\nthe reference taken during probe is balanced on both success and failure.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/6ad4892c4f5cb437a928a02f5b7d37d496aa9268","tags":[]},{"url":"https://git.kernel.org/stable/c/7eef9ae3b4ef782557526dd8ba0c206f028d8c2f","tags":[]},{"url":"https://git.kernel.org/stable/c/cb6b0b1a9d5a61ef841739d42c6211094e9c8e2c","tags":[]},{"url":"https://git.kernel.org/stable/c/e8ea01a0457080b0cc7c69c430c0ab65d84dc377","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
