Clang warns:

  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
  1 error generated.

device_node's assignment was removed but not all of its uses. Remove the
call to of_node_put() and the variable declaration to clean up the
warning.
