[PATCH] powermac: Call of_node_put(bk_node) only once in pmac_has_backlight_type()

[Markus Elfring <Markus.Elfring@web.de>]

From: Markus Elfring <elfring@users.sourceforge.net>

An of_node_put(bk_node) call was immediately used after a pointer check
for an of_get_property() call in this function implementation.
Thus call such a function only once instead directly before the check.

This issue was transformed by using the Coccinelle software.
