Subject: bonding: Remove unnecessary returned value check
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=3d67576da15167b2669e4765ca9e383f6bcb4171;p=openwrt%2Fstaging%2Fblogic.git

bonding: Remove unnecessary returned value check

The function bond_info_query alwarys returns 0. As such, in the function
bond_do_ioctl, it is not necessary to check the returned value. So the
interface type of the function bond_info_query is changed to void. The
redundant check is removed.
