From c2590f4a8ddf461d33ac2085d966432b2a6a09f2 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Mon, 18 Oct 2010 03:50:29 +0000 Subject: sh: clkfwk: modify for_each_frequency end condition The end condition of for_each_frequency should care about both clk_rate_table_round and clk_rate_div_range_round, and using "correct max size" is a natural idea in later function. To avoid data over flow, this patch didn't modify clk_rate_div_range_round side as .max = div_max + 1.
