Subject: [PATCH] pinctrl: samsung: Fix device node refcount leaks in S3C64xx
wakeup controller init
In s3c64xx_eint_eint0_init() the for_each_child_of_node() loop is used
with a break to find a matching child node. Although each iteration of
for_each_child_of_node puts the previous node, but early exit from loop
misses it. This leads to leak of device node.
