Hi All,

The builds of arm64 allmodconfig with clang have failed to build
next-20220830 with the error:

drivers/gpu/drm/msm/dsi/dsi_host.c:1903:14: error: variable 'device_node' is uninitialized when used here [-Werror,-Wuninitialized]
        of_node_put(device_node);
                    ^~~~~~~~~~~
drivers/gpu/drm/msm/dsi/dsi_host.c:1870:44: note: initialize the variable 'device_node' to silence this warning
        struct device_node *endpoint, *device_node;
                                                  ^
                                                   = NULL

git bisect pointed to 5f8cdece42ff ("drm/msm/dsi: switch to DRM_PANEL_BRIDGE")

I will be happy to test any patch or provide any extra log if needed.
