Subject: [PATCH 8/9 net-next-2.6] [TIPC]: Exclude debug-only print buffer code when not debugging
This patch modifies TIPC to only exclude debug-related print buffer
routines when debugging capabilities are not required. It also
fixes up some related #defines that exceed 80 characters.
Signed-off-by: Allan Stephens <allan.stephens@...driver.com>
