Subject: clk: divider: Fix clk_divider_round_rate() to use clk_readl()
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.
Fixes: e6d5e7d90be92cee ("clk-divider: Fix READ_ONLY when divider > 1")
