6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Javier Carrasco javier.carrasco.cruz@gmail.com
commit f708e8b4cfd16e5c8cd8d7fcfcb2fb2c6ed93af3 upstream.
Early exits (goto, break, return) from for_each_child_of_node() required an explicit call to of_node_put(), which was not introduced with the break if cnt == MAX_CRTC.
Add the missing of_node_put() before the break.
