From: Ian Morris <ipm@...rality.org.uk>
To: netdev@...r.kernel.org
Cc: Ian Morris <ipm@...rality.org.uk>
Subject: [PATCH net-next 4/4] ipv6: coding style - cleanse bracing
Tidy up braces in a few places (mainly if statements):
* remove unnecessary braces
* add braces for single line statements where part of an "else" where the other branch has braces
No change in the object output is detected by the objdiff script.
Signed-off-by: Ian Morris <ipm@...rality.org.uk>
