[PATCH 0/4] add missing of_node_puts

[Julia Lawall]

The device node iterators perform an of_node_get on each iteration, so a
jump out of the loop requires an of_node_put.

The patches for drivers/gpu/drm/imx/imx-ldb.c and
drivers/gpu/drm/sun4i/sun4i_backend.c contain some added of_node_puts for
which the need was identified manually.  Details are in the patch logs.
