Subject[PATCH] clk: imx6ul: fix missing of_node_put()
Date
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.

Signed-off-by: Nicholas Mc Guire <hofrat@osadl.org>
Fixes: commit 787b4271a6a0 ("clk: imx: add imx6ul clk tree support")
---

Problem located with experimental coccinelle script

Patch was compile tested with: imx_v6_v7_defconfig (implies
CONFIG_SOC_IMX6UL=y)

Patch is against 4.18-rc4 (localversion-next is next-20180713)
