Doc Text:	A flaw was found in the Intel SoundWire (sof_sdw) driver within the Linux kernel's ASoC subsystem. When a sound card registration fails, often due to deferred probing, the driver does not clean up associated device properties for headset codecs. This incomplete cleanup can lead to kernel crashes during subsequent device binding or unbinding operations. The underlying issue stems from the absence of proper error-handling logic in the registration process. A fix was introduced by adding a helper function that ensures all device properties are removed correctly, both during normal removal and when registration fails.	Story Points:	---

Description OSIDB Bzimport 2025-02-26 03:13:57 UTC

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

ASoC: Intel: sof_sdw: handle errors on card registration

If the card registration fails, typically because of deferred probes,
the device properties added for headset codecs are not removed, which
leads to kernel oopses in driver bind/unbind tests.

We already clean-up the device properties when the card is removed,
this code can be moved as a helper and called upon card registration
errors.
