Subject: net: udp: remove redundant initialization in udp_send_skb
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=cffb8f6177bbfc235e7054a4bb321b126b64205c;p=linux.git

net: udp: remove redundant initialization in udp_send_skb

The initialization for 'err' with 0 is redundant and can be removed,
as it is updated by ip_send_skb and not used before that.
