What it is

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.apply_idle_power_optimizations", which

dereferences null "dc->clk_mgr". (The function pointer resolves to

"dcn35_apply_idle_power_optimizations".)

This fixes 1 FORWARD_NULL issue reported by Coverity.
