[PATCH AUTOSEL 4.14 12/17] mips: ralink: Fix refcount leak in of.c

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Liang He <windhl@xxxxxxx>

[ Upstream commit 48ca54e39173d1ed4c4dc8cf045484014bb26eaf ]

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.
