From 2306f65637079c8922aec15b4ced75ea457e757b Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Fri, 26 Feb 2016 09:06:07 +0100 Subject: 6lowpan: iphc: fix invalid case handling This patch fixes the return value in a case which should never occur. Instead returning "-EINVAL" we return LOWPAN_IPHC_DAM_00 which is invalid on context based addresses. Also change the WARN_ON_ONCE to WARN_ONCE which was suggested by Dan Carpenter.
