Subject: [PATCH 5.17 1026/1126] rtc: gamecube: Fix refcount leak in gamecube_rtc_read_offset_from_sram

From: Miaoqian Lin <linmq006@...il.com>

commit 4b2dc39ca024990abe36ad5d145c4fe0c06afd34 upstream.

The of_find_compatible_node() function returns a node pointer with
refcount incremented, We should use of_node_put() on it when done
Add the missing of_node_put() to release the refcount.
