From adb552c31915415fdb374172085f174f459727ea Mon Sep 17 00:00:00 2001 From: Marc Kleine-Budde Date: Sun, 30 Jul 2017 23:51:01 +0200 Subject: can: raw: raw_bind(): bail out if can_family is not AF_CAN Until now CAN raw's bind() doesn't check if the can_familiy in the struct sockaddr_can is set to AF_CAN. This patch adds the missing check.
