Description

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

drm/amd/display: Add NULL check for clk_mgr and clk_mgr->funcs in dcn30_init_hw

This commit addresses a potential null pointer dereference issue in the
dcn30_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/dcn30/dcn30_hwseq.c:789 dcn30_init_hw() error: we previously assumed ‘dc->clk_mgr’ could be null (see line 628)
