From 5181b50fc89d321cf79ed2f2fff5bec0b55e3011 Mon Sep 17 00:00:00 2001 From: Evgeny Voevodin Date: Fri, 13 Apr 2012 11:39:06 +0000 Subject: [PATCH] hw/exynos4210_combiner.c: Drop excessive read/write access check. Access to reserved area at offset higher than 0x3c is allowed in External Combiner. Samsung Galaxy Kernel implements this. So, drop excessive checks in read/write functions.
