Subject: [PATCH] rtc: gamecube: Fix refcount leak in gamecube_rtc_read_offset_from_sram
Date:   Wed,  9 Mar 2022 09:22:25 +0000
Message-Id: <20220309092225.6930-1-linmq006@gmail.com>
Precedence: bulk

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.

Fixes: 86559400b3ef ("rtc: gamecube: Add a RTC driver for the GameCube, Wii and Wii U")
