From 8b19ae07616bbd18969b94cbf5d74308a8f2bbdf Mon Sep 17 00:00:00 2001 From: Mans Rullgard Date: Sat, 8 Oct 2011 01:59:51 +0100 Subject: crc: fix signed overflow This fixes a signed overflow from i << 24 when i == 255 by making i unsigned. The result of the shift is already assigned to an variable of unsigned type.
