Subject: [PATCH] amba: bus: fix refcount leak
Git-commit: e312cbdc11305568554a9e18a2ea5c2492c183f3
Patch-mainline: v6.6-rc1
References: git-fixes

commit 5de1540b7bc4 ("drivers/amba: create devices from device tree")
increases the refcount of of_node, but not releases it in
amba_device_release, so there is refcount leak. By using of_node_put
to avoid refcount leak.
