From: dingtianhong Date: Thu, 2 Jan 2014 01:13:12 +0000 (+0800) Subject: bonding: remove the return value for bond_3ad_bind_slave() X-Git-Tag: Ubuntu-5.2.0-15.16~14144^2~332^2~1 X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=359632e54427055ca5a9c2a849ea09d131540acb;p=mirror_ubuntu-eoan-kernel.git bonding: remove the return value for bond_3ad_bind_slave() I'm sure the operand slave and bond for the function will not be NULL, so the check for the bond will not make any sense, so remove the judgement, and the return value was useless here, remove the unwanted return value. The comments for the bond 3ad is too old, cleanup some errors and warming. Signed-off-by: Ding Tianhong Signed-off-by: David S.
