4.4-stable review patch. If anyone has any objections, please let me know.
------------------ From: Geert Uytterhoeven <[email protected]> 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.
