Subject: mips: ralink: Fix refcount leak in of.c
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=48ca54e39173d1ed4c4dc8cf045484014bb26eaf;p=linux.git

mips: ralink: Fix refcount leak in of.c

In plat_of_remap_node(), plat_of_remap_node() will return a node
pointer with refcount incremented. We should use of_node_put()
when it is not used anymore.
