NULL Pointer Dereference

Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
drm/amd/display: Add NULL check for clk_mgr and clk_mgr->funcs in dcn401_init_hw<br />
<br />
This commit addresses a potential null pointer dereference issue in the<br />
`dcn401_init_hw` function. The issue could occur when `dc->clk_mgr` or<br />
`dc->clk_mgr->funcs` is null.<br />
<br />
The fix adds a check to ensure `dc->clk_mgr` and `dc->clk_mgr->funcs` is<br />
not null before accessing its functions. This prevents a potential null<br />
pointer dereference.<br />
<br />
Reported by smatch:<br />
drivers/gpu/drm/amd/amdgpu/../display/dc/hwss/dcn401/dcn401_hwseq.c:416 dcn401_init_hw() error: we previously assumed &#39;dc->clk_mgr&#39; could be null (see line 225)
