[PATCH 4.8 092/125] clk: divider: Fix clk_divider_round_rate() to use clk_readl()
From: Greg Kroah-Hartman
Date: Sat Oct 29 2016 - 10:06:09 EST
4.8-stable review patch. If anyone has any objections, please let me know.
------------------
From: Geert Uytterhoeven <geert+renesas@xxxxxxxxx>
commit 2cf9a57811bddb6fa6b0f8d7376da164d5534813 upstream.
clk-divider uses clk_readl()/clk_writel() everywhere, except in
clk_divider_round_rate(), where plain readl() is used. Change this to
clk_readl(), as it makes a difference on powerpc.
