Subject: [PATCH] drm/display: fix possible null-pointer dereference in
dcn10_set_clock()
The variable dc->clk_mgr is checked in:
if (dc->clk_mgr && dc->clk_mgr->funcs->get
The variable dc->clk_mgr is checked in:
if (dc->clk_mgr && dc->clk_mgr->funcs->get_clock)
This indicates dc->clk_mgr can be NULL.
However, it is dereferenced in:
if (!dc->clk_mgr->funcs->get_clock)
To fix this possible null-pointer dereference, check dc->clk_mgr before
dereferencing it.
