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

ASoC: qcom: q6apm: move component registration to unmanaged version

q6apm component registers dais dynamically from ASoC toplology, which
are allocated using device managed version apis. Allocating both
component and dynamic dais using managed version could lead to incorrect
free ordering, dai will be freed while component still holding references
to it.

Fix this issue by moving component to unmanged version so
that the dai pointers are only freeded after the component is removed.
