This patch corrects two problems in the display of error code information in TIPC messages when debugging: - no longer tries to display error code in NAME_DISTRIBUTOR messages, which don't have the error field - now displays error code in 24 byte data messages, which do have the error field Signed-off-by: Allan Stephens <allan.stephens@windriver.com> Signed-off-by: David S.
