Commit 8a2fa38f removed the mode_fixup because it was empty,
but 652353e6 modified it to call drm_mode_set_crtcinfo()
instead.

Both commits are correct, but the merge of the two kept the nonempty
version without the reference to it, as shown by the gcc warning:

drm/panel: Changes for v4.6-rc1

This contains a refactoring of parts of the DSI core to allow creating

a few cleanup patches.

drm/tegra: Changes for v4.6-rc1

Only two cleanups this time around. One fixes reference counting of
device tree nodes, the other changes the return value of a function
from an unsigned int to an int to reflect that it will return error
codes.

for_each_child_of_node() performs an of_node_get() on each iteration, so
to break out of the loop an of_node_put() is required.

Found using Coccinelle. The semantic patch used for this is as follows:

The behavior was accidentally introduced in a patch described as "This is

As far as I can tell, that was true for the rest of that patch except for
this one function, which has been changed to a NOP.
