[PATCH 4.18 029/235] clk: imx6sll: fix missing of_node_put()

[Greg Kroah-Hartman]

4.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Nicholas Mc Guire <hofrat@xxxxxxxxx>

[ Upstream commit 7f5eac5934d747535f9ffc997792a0a6eb289374 ]

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.
