From 7d36b9c102318aa86aceb074359305da88ce9ef9 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Wed, 19 Oct 2016 20:49:39 +0900 Subject: clk: uniphier: fix memory overrun bug The first loop of this "for" statement writes memory beyond the allocated clk_hw_onecell_data. It should be: for (clk_num--; clk_num >= 0; clk_num--) ... Or more simply: while (--clk_num >= 0) ...
