CVE-2024-49907: drm/amd/display: Check null pointers before using dc->clk_mgr
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".)
