Return-Path: From: Alexander Aring To: linux-wpan@vger.kernel.org Cc: linux-bluetooth@vger.kernel.org, kernel@pengutronix.de, dan.carpenter@oracle.com, Alexander Aring Subject: [PATCH bluetooth-next] 6lowpan: iphc: fix invalid case handling Date: Fri, 26 Feb 2016 09:06:07 +0100 Message-Id: <1456473967-26721-1-git-send-email-aar@pengutronix.de> Sender: linux-wpan-owner@vger.kernel.org List-ID: 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.
