UBUNTU-CVE-2024-49907: Medium severity ubuntu/linux-azure vulnerability
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Check null pointers before using dc->clkmgr [WHY & HOW] dc->clkmgr is null checked previously in the same function, indicating it might be null. Passing "dc" to "dc->hwss.applyidlepoweroptimizations", which dereferences null "dc->clkmgr". (The function pointer resolves to "dcn35applyidlepoweroptimizations".) This fixes 1 FORWARDNULL issue reported by Coverity.
