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.
