[PATCH AUTOSEL 4.18 16/88] clk: imx6ul: fix missing of_node_put()

[Sasha Levin]

From: Nicholas Mc Guire <hofrat@xxxxxxxxx>

[ Upstream commit 11177e7a7aaef95935592072985526ebf0a3df43 ]

of_find_compatible_node() is returning a device node with refcount
incremented and must be explicitly decremented after the last use
which is right after the us in of_iomap() here.
