Felix Gu 871630255e drm/logicvc: Fix device node reference leak in logicvc_drm_config_parse() ...

[ Upstream commit fef0e649f8 ]

The logicvc_drm_config_parse() function calls of_get_child_by_name() to
find the "layers" node but fails to release the reference, leading to a
device node reference leak.

Fix this by using the __free(device_node) cleanup attribute to automatic
release the reference when the variable goes out of scope.
