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, indicatingit might be null.Passing "dc" to "dc->hwss.apply_idle_power_optimizations", whichdereferences null "dc->clk_mgr". (The function pointer resolves to"dcn35_apply_idle_power_optimizations".)This fixes 1 FORWARD_NULL issue reported by Coverity.
