From 4a1728a28a193aa388900714bbb1f375e08a6d8e Mon Sep 17 00:00:00 2001 From: Petko Manolov Date: Tue, 15 Nov 2005 09:48:23 +0200 Subject: [PATCH] USB: usb-net: removes redundant return removes all redundant collecting of the return value from get/set_registers() and suchlike. can't remember who put all of those some time ago, but they doesn't make any sense to me. where needed only a few references remained;
