+Subject: net: ieee802154: return -EINVAL for unknown addr type
+
+From: Alexander Aring <aahringo@redhat.com>
+
+commit 30393181fdbc1608cc683b4ee99dcce05ffcc8c7 upstream.
+
+This patch adds handling to return -EINVAL for an unknown addr type. The
+current behaviour is to return 0 as successful but the size of an
+unknown addr type is not defined and should return an error like -EINVAL.
+
+Fixes: 94160108a70c ("net/ieee802154: fix uninit value bug in dgram_sendmsg")
