From 998396be9ceeb6d02127d9ae6ce1cb6b3659a25d Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Wed, 26 May 2010 07:37:57 +0100 Subject: [PATCH] ARM: 6144/1: TCM memory bug freeing bug commit ea208f646c8fb91c39c852e952fc911e1ad045ab upstream. This fixes a bug in mm/init.c when freeing the TCM compile memory, this was being referred to as a char * which is incorrect: this will dereference the pointer and feed in the value at the location instead of the address to it. Change it to a plain char and use &(char) to reference it.
