From a016892cd6eb8d3dd9769021b088917ac7371abd Mon Sep 17 00:00:00 2001 From: Allan Stephens Date: Fri, 31 Dec 2010 18:59:35 +0000 Subject: tipc: remove extraneous braces from single statements Cleans up TIPC's source code to eliminate the presence of unnecessary use of {} around single statements. These changes are purely cosmetic and do not alter the operation of TIPC in any way. Signed-off-by: Allan Stephens Signed-off-by: Paul Gortmaker Signed-off-by: David S.
