From 7b2185747c32260a3e43b94812e96d22a8725f09 Mon Sep 17 00:00:00 2001 From: "Denis V. Lunev" Date: Thu, 31 Jan 2008 18:47:00 -0800 Subject: [IPV4]: Small style cleanup of the error path in rtm_to_ifaddr. Remove error code assignment inside brackets on failure. The code looks better if the error is assigned before condition check. Also, the compiler treats this better. Signed-off-by: Denis V. Lunev Signed-off-by: David S.
