Subject[PATCH] drm/msm/dsi: Remove use of device_node in dsi_host_parse_dt()
Date
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.
