[PATCH AUTOSEL 5.15 02/42] ARM: rockchip: Add missing of_node_put() in rockchip_suspend_init()

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

 



From: Liang He <windhl@xxxxxxx>

[ Upstream commit f4470dbfb5ff92804650bc71d115c3f150d430f6 ]

In rockchip_suspend_init(), of_find_matching_node_and_match() will
return a node pointer with refcount incremented. We should use
of_node_put() in fail path or when it is not used anymore.
