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

drm/amd/display: Add NULL check for clkmgr and clkmgr->funcs in dcn401inithw

This commit addresses a potential null pointer dereference issue in the dcn401_init_hw function. The issue could occur when dc->clk_mgr or dc->clk_mgr->funcs is null.

The fix adds a check to ensure dc->clk_mgr and dc->clk_mgr->funcs is not null before accessing its functions. This prevents a potential null pointer dereference.

Reported by smatch: drivers/gpu/drm/amd/amdgpu/../display/dc/hwss/dcn401/dcn401hwseq.c:416 dcn401inithw() error: we previously assumed 'dc->clkmgr' could be null (see line 225)
