From 6ad4892c4f5cb437a928a02f5b7d37d496aa9268 Mon Sep 17 00:00:00 2001 From: Haoxiang Li Date: Mon, 22 Jun 2026 22:56:45 +0800 Subject: [PATCH] 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.
