Subject: net: remove unnecessary return's
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=2045ceaed4d54e6e698874d008be727ee5b2a01c;p=linux-beck.git

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.
