mtd: maps: Fix refcount leak in of_flash_probe_versatile
[ Upstream commit 33ec82a6d2b119938f26e5c8040ed5d92378eb54 ]
of_find_matching_node_and_match() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.
Fixes: b0afd44bc192 ("mtd: physmap_of: add a hook for Versatile write protection")
