DEBIAN-CVE-2024-56580

In the Linux kernel, the following vulnerability has been resolved: media: qcom: camss: fix error path on configuration of power domains There is a chance to meet runtime issues during configuration of CAMSS power domains, because on the error path devpmdomaindetach() is unexpectedly called with NULL or error pointer. One of the simplest ways to reproduce the problem is to probe CAMSS driver before registration of CAMSS power domains, for instance if a platform CAMCC driver is simply not built.
