[PATCH] clk: imx6sll: fix missing of_node_put()
From: Nicholas Mc Guire
Date: Fri Jul 13 2018 - 12:44:30 EST
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@xxxxxxxxx>
Fixes: commit 4a5f720b6542 ("clk: imx: add clock driver for imx6sll")
---
Problem located with experimental coccinelle script
looks like cut&past error from imx6ul (or vice versa)
Patch was compile tested with: imx_v6_v7_defconfig (implies
CONFIG_SOC_IMX6SLL=y)
Patch is against 4.18-rc4 (localversion-next is next-20180713)
