From: Colin Ian King <colin.king@xxxxxxxxxxxxx> [ Upstream commit 291ddeb621e4a9f1ced8302a777fbd7fbda058c6 ] Currently the switch statement for format->cpp[0] value 4 assigns color_index which is never read again and then falls through to the default case and returns. This looks like a missing break statement bug. Fix this by adding a break statement.
