Summary
drm/amd/display: Check null pointers before using dc->clk_mgr
Details

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

drm/amd/display: Check null pointers before using dc->clk_mgr

[WHY & HOW] dc->clk_mgr 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 FORWARD_NULL issue reported by Coverity.
