Subject: net: socket: use pr_info_once to tip the obsolete usage of PF_PACKET
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f3c986908cc3b369b57f75de306c635a0074b76b;p=linux-beck.git

net: socket: use pr_info_once to tip the obsolete usage of PF_PACKET

There is no need to use the static variable here, pr_info_once is more
concise.
