From: Alexander Aring Date: Wed, 2 Sep 2015 12:21:18 +0000 (+0200) Subject: ieee802154: 6lowpan: remove check on null X-Git-Tag: KARO-TX6UL-2015-11-03~90^2~277^2~36 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=2c88b5283f60d09d41b9fe03351c0d2e8eef904f;p=karo-tx-linux.git ieee802154: 6lowpan: remove check on null This patch removes one check on null which should be already done by checking before for ARPHRD_IEEE802154. All ARPHRD_IEEE802154 and ARPHRD_IEEE802154_MONITOR should have wdev->ieee802154_ptr, where ARPHRD_IEEE802154 is currently a node interface only.
