Subject: [PATCH 4.10 15/27] hwrng: omap - use devm_clk_get() instead of of_clk_get()

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

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

From: Thomas Petazzoni <thomas.petazzoni@...e-electrons.com>

commit 761c2510283066324cab7859930777ee34cbca78 upstream.

The omap-rng driver currently uses of_clk_get() to get a reference to
the clock, but never releases that reference. This commit fixes that by
using devm_clk_get() instead.
