From 2045ceaed4d54e6e698874d008be727ee5b2a01c Mon Sep 17 00:00:00 2001 From: stephen hemminger Date: Wed, 12 Feb 2014 20:51:22 -0800 Subject: [PATCH] net: remove unnecessary return's One of my pet coding style peeves is the practice of adding extra return; at the end of function. Kill several instances of this in network code. I suppose some coccinelle wizardy could do this automatically. Signed-off-by: Stephen Hemminger Signed-off-by: David S.
